Great second book in the series, I liked it even better than the first one! Sloan McPherson is a great character, with solid development. I’m excited for the next entry in the series!

I had not read any previous books in this series but from the background story it seems that there was at least one. I found the main character a bit one layered and tough to have her carry you through the story. That may have been because I was just introduced to her in this novel. The diving aspect was interesting as was the mystery as to what happened to those teenagers all those years ago.
I loved the book cover which is what drew me to the story but found it a chore at times to keep going and follow the plot as I didn’t feel connected to the characters. It seemed one dimensional.

Mystery

Finding a new author or series that I get excited about turns me into a kid on Christmas. These Underwater Investigation Unit books are my newest addiction. They are just spectacular. Mayne starts off each book with a bang and keeps us on edge excitedly turning pages to an exhilarating conclusion.

Sloan gets called to a site to dive and collect a body from a car crash. The issue, it's a major alligator hang out and the biggest gator in the area has recently been sighted in the pond. Sloan recovers the body not without some hair-raising events and runs head first into an even bigger mystery. This one having roots from 30 years ago.

I don't want to say too much about the new case the team gets involved in and spoil anything. Suffice it to say, it's certainly juicy. This book centers around Sloan, so we don't get as many interactions with her colorful family, but we do get an addition to George and Sloan's team - Hughes. He makes a great addition and is a great counterpoint to Sloan and George. We learn enough of Hughes' backstory to know that there is a lot more to him.

Centering these investigations around the ocean was a brilliant move by Mayne and adds so much to the story. The sea and all its creatures are a mystery to many of us and Sloan's adventures under the water add a great element of atmosphere that sets this series on it's own outstanding level.

If you are a mystery/thriller fan at all - these books are a MUST!

Thank you to NetGalley and Thomas & Mercer for my ARC of this book.

Well that was something different and hugely enjoyable. 4.5 stars rounded down to 4(explained later and a minor gripe stopping it being a 5 star read)

Sloan McPherson is a police diver working in Florida. She works for the Underwater Investigative Unit and is assigned to a case of a car going off a bridge into a pond.

When she dives and discovers the car, she also discovers a van with four bodies inside nearby. It turns out they are the bodies of four young local people that went missing 30 years ago after returning from a rock concert. Everyone writes it off as an accident but Sloan, despite warnings to leave it alone, follows all the leads and believes they were murdered. When she links them to previous historical missing person cases, she is convinced she has stumbled across a serial killer from the past.
When a fresh female body is discovered shortly afterwards in the Everglades she knows the killer is still alive and, the news of his past may have awakened his dormant killing spree. Can she and her team catch the killer before he kills again or worse, catches up with Sloan?

This was a hugely enjoyable take on the thriller/police procedural/ serial killer genre. The whole underwater team thing sounded quite niche when I read about it in the blurb but it works perfectly and gives a nice fresh angle on the genre.

Sloan is a fantastic central character and carries the book extremely well, despite her youth, her flaws and her mistakes along the way.

The story is excellently put together and told. No fat on this one. Pacing too was excellent. Plenty of room for the story to breath but while at the same time always being a page turner.

I loved the ending too. I feared I may have been set up for a disappointment but it ended beautifully.
My only minor gripe with the book was, too often her superiors made stupid calls and decisions, the opposite of what she wanted to do and , while occasionally they were right and pointing out her lack of experience, mostly it felt forced and more a plot device than based in reality. It’s a very minor gripe though and only accounts for a tiny portion of the book.

I haven’t read the first I’m this series but will be definitely seeking it out.
If you enjoy this genre(which I do immensely) and are looking for something a little different then this one is definitely for you.

Many thanks to Netgalley, Andrew Mayne and Thomas and Mercer for an ARC in exchange for an honest review

Another Heart-Stopping Thriller for the Detective Sloan McPherson

The heroine, Detective Sloan McPherson, arrives at the scene where a vehicle went in a small lake. She was on call for law enforcement diver support. Her job here was to recover the body in a submerged vehicle. She recognizes this location and asks if this is Pond 65. Pod 65 is a popular spot for alligators, especially for Big Bill, a 1,000 pounds and 13 feet apex predator. Of course, Big Bill makes an appearance during the recovery operations. As Sloan evades Big Bill, she swims headfirst into a sunken SUV. When she makes it to shore sans Big Bill, her gut tells her that the body just pulled from the lake wasn’t the only one in this lake. I was hooked from this point on.

The main storyline is jammed packed with action with intervals of inter law enforcement agency squabbles and detective work on competing investigations on multiple murders and yacht equipment thieves. All of these aspects are mixed into an engaging story with adequate twists and turns in each of the above aspects. I wanted to continue to read this novel late into the night.

In this novel, a new character is introduced. A new hire for the Underwater Investigation Unit (UIU) Scott Hughes is a former Navy diver with local police experience. Sloan believes he was added to counterbalance her adventurous underwater activity, not an unreasonable assumption.

The B-storyline is as rich as the first novel in the series. There is a little less on her father but more detail with Run, Sloan’s boyfriend and father to her daughter, and the daughter, Jackie. For Scott, his character goes from supporting to a contributing member of the UIU; much is learned about him and his relationship with his wife and daughter. These storylines increased my enjoyment in reading this novel.

There are not any graphic intimate scenes. There are murders with a serial murderer, but almost all violence is described after the fact so it is not as edgy. There is low but definite level of foul language. These aspects never rose to noticeable level for me. As this is the second book in the series, I found all references to events in the first book were adequately explained so this book could be read before the first novel in this series.

There is one aspect that some readers may find objectionable. Even Sloan states that her diving has many bad habits that are deeply ingrained in her. I read one review on the author’s first novel that diving was just implausible to downright dangerous. My thoughts are that this is not true crime, and I am reading this novel for entertainment. These questionable scenes increased my heartrate and intensified my thrill in the action. I see these as pluses and not minuses.

Overall, this novel is a great summer read as it sure kept my interest through to the end. I am eagerly waiting for the next novel in the series. I rate this novel with five stars.

I have received a free e-book version of this novel through NetGalley from Thomas & Mercer with an expectation for an honest, unbiased review. I wish to thank Thomas & Mercer for the opportunity to read and review this novel early.

This is book two in the series. This one doesn’t have quite as much action as the first one. It had a good mystery, I thought the ending was a bit rushed. I still enjoyed the book and look forward to the next one.
Thanks to Netgalley and the publisher for the early copy

This book is so good. I just needed to start with that.

A few months ago I had the opportunity to read the first book in this series, The Girl Beneath the Sea, and I became immediately immersed into this world of underwater investigations. I loved the story, the characters, everything. When I saw the opportunity to read this second book, I grabbed it, hoping it would be as good as the first.

It delivered. Sloan McPherson continues to develop into a badass underwater investigator, aided by her mentor Solar. Their unit even has a new hire, Hughes, who is an excellent addition, more thoughtful than Sloan, but just as motivated. The three of them stumble onto a serial killer, and have to do some serious investigating, above and under water, to not only prove they can handle the case, but catch this pretty horrific murderer.

The pacing of this book is perfect - you’re kept on your toes, and constantly engaged in what’s going on. The writing immerses you completely in the story, whether that’s with Sloan underwater trying to gather evidence while keeping a giant alligator at bay, or trekking through the Everglades in an attempt to hunt a killer’s lair. Added to that is the suspense and mystery portion, which is just enough of a challenge to the reader to keep you pulled in.

The parts of those story I loved the most were the underwater portions - the descriptions are vivid, and Sloan is in her element. I would actually have preferred more of that, because it’s just so well done, and sets this series apart from others. The UIU needs to be featured! Along that note, the side case seemed a bit of an afterthought, and could have been incorporated better.

The other component of the story that I loved, though, was the interactions between Sloan and the important people in her life, Jackie and Run. These glimpses make her more real, and add an interesting dimension to her character. They’re very much appreciated by me, and I’d love for this development to continue.

A final note before I wrap this up is about the ending. It felt a bit rushed, like there should be one more chapter before the epilogue. Please, show that resolution, maybe even Sloan and company finally getting some respect from the other law enforcement members they’ve tangled with. Even if not this, there needs to be something, because it’s too abrupt as is.

Ultimately, I cannot recommend this book -and it’s predecessor- enough. Read it. You will not be disappointed by these characters and events that unfold around them.

Black Coral is the second book in a series about Florida underwater diving detective, Sloan McPhearson. This was a fun fast-paced read with lots of twists and turns. A def brain candy book. I look forward to, hopefully, a third in the series! Thank you to Netgalley and the Publishers for a chance to read this book!

An excellent follow-up to the first installment of the Underwater Investigation Unit series. Mayne brings back our favorite dysfunctional privateer family and introduces an exciting cold case the UIU works with other agencies to solve.

The writing has matured in this book and the storytelling is fast-paced and engaging. Mayne does an amazing job with atmospheric prose and you really feel like you're with Sloan in the Everglades and during her dives. I can't wait for book 3!

I couldn’t finish the book. I had a hard time getting into the plot and connecting with the characters. I put it down more times than I picked it up.

I really enjoy a book that takes hold of you from page 1 to the end. This is that type of book. Sloan McPherson is an underwater detective for the Underwater Investigation Unit. She and her team discover a van with 4 teenagers that has been in a pond for many years. Every one believes that this was a fatal accident caused by drug use or reckless driving, but Sloan suspects that it is murder. Add to this a new murder has happened and Sloan believes the 2 are connected. Problem is the suspect knows that Sloan is moving in and will do anything not to get caught.
With all the twists and turns of the plot, I was engrossed from start to finish!
I would recommend.

This second entry in Mayne's "Underwater Investigation Unit" series continues the riveting blend of adventure and thrills. Sloan McPherson is a police diver with keen intuition and blunt social skills. In the course of finding answers in one case, she discovers a van underwater filled with four dead teenagers who disappeared 30 years ago.

In South Florida, alligators generously populate the waters. Sloan takes on "Big Bill" in a tense and propulsive early scene. There is tremendous pressure to solve the crimes while battling bureaucracy between law enforcement agencies. Sloan is no slouch and combats sexism, breaks rules, and follows her gut, steadily making inroads where others have failed. Then she heads to the gator and snake-infested Everglades. There are more bodies. Many more bodies.

When a man convincingly confesses, Sloan and her small three-person team press on and ultimately face down the worst serial killer in Florida's history. This is fast-paced with some exciting and taut confrontations. Sloan is a fine character with a colorful family.

This series is perfect for readers who love mysteries and also a fast paced story. I had to finish this story in one day. The main character is such a badass!

This book kept me captivated till the very last page. Very Suspenseful! Even my husband would love it and he doesn't like to read!

Loved this one . I just love all Maynes books. I loved the setting and the main characters and they always have good plots.
Thanks for letting me review this book

This book was such a fun and wild, wild ride. I'd highly recommend reading the first book in this series. I absolutely adored the setting and how the author described Florida and the gloomy pond. Overall, this was a thrilling installment in the underwater investigation series and I would recommend to thriller readers who are craving an interesting and atmospheric setting.

Sloan Patterson is a detective and a diver. While out on a boat burglary case her and her team recover a van with 4 bodies of teenagers in it. First it is thought to be an accident, but Sloan proves it was murder decades ago. When another body is discovered, Sloan determines a serial killer is still active. I enjoyed this book because it was different. I've read many mystery and thrillers but never from a diving perspective. Something new and interesting.

Great book a really enjoyable serial killer thriller. Having previously read Andrew Mayne's Jessica Blackwood series ( highly reccomend ), i thought I would dip my toe into his UIU books with the heroine Sloan Mcphereson. What starts off as a routine salvage dive in the Everglades, turns into a manhunt for a serial killer who has been active for 30 years. Highly recommend.

I like this book a lot better than the first Underwater Investigation Unit book ("The Girl Beneath the Sea"). In all fairness, stories about catching serial killers interest me more than stories about mafia ties.

I really enjoyed reading this book. I really liked Hughes as an addition to the UIU; I thought he fit in with Sloan and George really well, and was a great asset to the team. I wish there was more George Solar in this one though; it felt like he was kind of stuck on the sidelines during most of the book (but that also allowed Sloan more time to get to know Hughes and it shaping him to become a valuable asset to the team, so that was a plus).

It is crazy just much finding those four kids was the tip of the iceberg for uncovering the Swamp Killer. It was some Ted Bundy level of craziness. I do wish that the story had circled back to get more closure about what had exactly happened that night with the kids in the van. Were they definitely his first victims? Did he plan their murder, or was is spontaneous? Did he always plan to put them in Pond 65? I did think that the openness at the end worked, but I wanted more answer from Stephen Dunn. How many people were in the swamp? Did he ever admit to a total number of victims?

Overall a very good read, I would definitely read another UIU book.

I love Andrew Mayne's books, from Jessica Blackwood to Theo Cray to the Underwater Investigations Unit! I was not disappointed by the latest about the UIU. Sloan McPherson has a little pirate in her, even if she is working on the right side of the law. The juxtaposition of her working on her PhD in archaeology while also serving as police detective (who just happens to dive) works well. Great story with fun characters.
