Another awesome suspense from Ruth Ware! She does an excellent job of keeping readers on the edge of their seats throughout this book. At times, the reader feels as tired as the main character from all the running she does and narrow escapes. Ware doesn't miss out on great character development though. The main character has many layers readers will work through and will sympathize with her grief and shock from losing her soul mate in such a terrible way, but will also feel her need to go on at any cost to find out the truth. While I am a huge fan of all of Ruth's books, this one felt a little more action packed and a little deeper with character development. Great read!

Let me start by saying that I am
A huge fan of this author but this book did not do it for me
This thriller is very much like every other thriller and not what has come to be expected from the author I had to check part way through that I was in fact reading a Ruth Ware book because it was so predictable which is not how I would describe previous works.
I enjoyed the ride even though I was increasingly agitated at the wound getting more character development than any character and I grew weary of reading the same line about our main character not being able to cry.
All in all, it was just ok for me and I realize I will be in the minority so I will recommend this book to others even though I had been expecting much more
Thank you netgally for an advanced opportunity to read this book

Although this is a bit different from Ware’s usual style, she completely nailed it with the Mr. and Mrs. Smith and Fugitive vibes—they came through loud and clear in this book. I was pulled into the story quickly, and was surprised that the tech stuff wasn’t overwhelming.

Jack (Jacintha) Cross and her husband are penetration testers, working together to identify any weak spots in the physical and online security systems of companies. Jack handles the buildings, while Gabe hacks into the computers. But when a job goes wrong, Jack has to deal with an issue that delays her, and she comes home to find her husband murdered, and she’s the prime suspect.

She quickly goes on the run, convinced that she’ll be able to find the real killer on her own, rather than trust the police, who don’t seem to believe her and aren’t investing much other than trying to tie her to the murder. And the evidence does seem to be pointing towards her as the main suspect.

Jack’s search was exciting and full of action, and while I was able to figure out some of the reveal, I was surprised by a lot more of the information presented towards the end of the book. I couldn’t put the book down, and this one was definitely a hit. Ware even managed to make the tech information manageable for people who aren’t tech-savvy, like me.

Another heart pounding, page turner and suspenseful novel by Ruth Ware!! This time taking on computer hackers Ware is at her best. Thanks for the advanced copy!!

Zero Days by Ruth Ware is a non-stop thrill ride and page turner! I read the book in no time at all. I couldn't put it down. Jack and Gabe Cross are PEN Testers adept at all things technology and security.. When Jack comes home to find her husband has been murdered and she is the main suspect, she realizes she is the only one who can exonerate herself. As Jack begins to investigate, she has many close calls that left me on the edge of my seat. I would highly recommend this book! Thank you to NetGalley and Gallery/Scout Press for the ARC!

This book is definitely a five star plus read! I will recommend Zero Days over and over again. I always praise her books to everyone I know....and to strangers (because they aren't strangers once you begin talking about books and authors!) I'm just wowed by Ruth Ware. I love her books, and she has outdone herself with. Zero Days. I didn't want to put it down, but when I had to it was all I could think about! I appreciate the richly detailed plot, setting, characters, and suspense! Pen testing is something I've heard of but not in such detail. What a great occupation for Jake. I'm going to need to re-read Zero Days multiple times while I wait for this author's next book. I truly can't wait!

You know when you read a book and can see it immediately on a screen? That's the sensation that I got from Ruth Ware's Zero Days, a twisty thriller about a security tester who finds herself in a bad situation. Jack is a "pen tester"—someone who breaks into places for a living to reveal their weaknesses. When her husband dies under mysterious circumstances, she has to figure out a way to exonerate them both, quickly. Her adventures on the lam are riveting—this is a book you can easily finish in a day, in giant gulps.

"The New York Times bestselling "new Agatha Christie" (Air Mail) Ruth Ware returns with this adrenaline-fueled thriller that combines Mr. and Mrs. Smith with The Fugitive about a woman in a race against time to clear her name and find her husband's murderer.

Hired by companies to break into buildings and hack security systems, Jack and her husband, Gabe, are the best penetration specialists in the business. But after a routine assignment goes horribly wrong, Jack arrives home to find her husband dead. To add to her horror, the police are closing in on their suspect - her.

Suddenly on the run and quickly running out of options, Jack must decide who she can trust as she circles closer to the real killer in this unputdownable and heart-pounding mystery from an author whose "propulsive prose keeps readers on the hook and refuses to let anyone off until all has been revealed" (Shelf Awareness)."

Because I know you need a Ruth Ware fix and no matter how many books say they're like her, there really is only one Ruth Ware.

Ware’s usual good writing of a crime thriller but with a technology twist. I can’t attest to the accuracy of the technology side but the story is good and the characters well written, though I wish the early development of Jack was better in terms of the obsessive behavior towards her by the ex boyfriend. Jack and her husband are freelance hackers, he in cyber and she in security, that are hired to penetrate businesses to understand their security weaknesses. Then a job goes wrong and Jack is on the run from the police. Good twists and sufficient red herrings to keep the reader on their toes.

Thought this was very fast-paced and well-written. I had a hard time putting it down and curled up on my couch in the middle of the day to finish it. That said, I didn't find the twist particularly surprising but still enjoyed getting to the end all the same.

Thanks to Netgalley and Gallery/Scout Press for gifting me an early copy. Below you'll find my honest review.

This was quite a change for Ruth Ware - it was more technothriller/fugitive mystery than her typical Christie-adjacent flare. Honestly though? I enjoyed it. It was a little obvious who the killer was, in my opinion, and the pacing had some issues that could have been adjusted, but all in all, I really liked it. Just keep in mind that it's different than her usual stuff, and go in with an open mind.

Four stars! Recommended for fans of Ruth Ware, Dan Brown, technothrillers, etc.

Thank you to NetGalley and the publisher for this advance review galley of Zero Days by Ruth Ware. Ware has done it again! I couldn't put this book down once I started it, and I lost a significant amount of sleep during that couple days! Zero Days hooks you from the very first scene -- which, cleverly, isn't at all what you think it is -- and keeps you on the line until the very end. A fitting thriller for the twenty-first century, this novel taught me just how much I don't know about technology, and also taught me to be very afraid of what I do know! This book is both entertainment and a cautionary tale for our times. I highly recommend this and all of Ruth Ware's other fantastic thrillers!

Another wild ride by Ruth Ware!! Jack is married to Gabe and when she comes home from a successful job, she finds her husband dead. She calls the police but all eyes are pointing to her. Jack knows that to set herself free, she has to find the person actually responsible for Gabe's death.

Thank you, NetGalley, for an advanced copy of this novel!

Thank you to Gallery Books for the arc in exchange for review.

This was not what I expected, a fast paced Mr & Mrs Smith type esque thriller, however predictable it was. I did enjoy my time reading it.

This book was a little disappointing to me. I typically love Ruth Ware and her writing style however this book was just not as enthralling as most of her other novels. I wasn't invested in the characters or the plot of this book as they were in my opinion very one dimensional and kind of boring honestly. The hacker plot wasn't very interesting to me either and the plot twist at the end was the most predictable I have seen in a Ware book.

I stayed up until 2am last night to finish this book, not because I had any sort of deadline or anything, but because I wanted to find out what came next. It has been a long time since I read a book that I couldn’t put down. I’ve read 3 Ruth Ware books so far, but this one is definitely the best. It will keep your on your toes, guessing who might be Gabe’s killer. I definitely recommend starting earlier in your day or you may find yourself staying up until 2am, too.

Thank you NetGalley and Gallery Books for the opportunity to read this book in advance of publication.

Love Ruth Ware and this did not disappoint. Very creative plot and of course a few twists to make it more fun!

I honestly don't know why I read thrillers. I always feel so nonplussed at the end. This was...exactly what I find in ever other thriller. Nothing new. And sadly it lost a lot of ground when it gave in to the surprise pregnancy after the husband dies trope. I think that one's been more than played.
Most disappointing, the main character in the book, the supporating side wound, that takes up PAGES of the story line didn't make it.

"Zero Days" is another success from Ruth Ware! She is the queen of thrills and plot twists, and fans will be thrilled with her newest addition.

This is a typical Ruth Ware. Mystery and suspense at its finest. I had a hard time putting this book down. The character development started fast and I instantly felt like I had a connection with the main character. Through all the trials and tribulations…sorry no spoilers here….I felt like I was with her every step of the way. This book is a definite must-read.
