Treble at the Jam Fest is a fun little cozy mystery. Erin Murphy manages the family Mercantile, though it seems to be more of a gourmet food shop, in a small town in Montana. She has a boyfriend, Adam, and her family is also prominently involved in the story. The characters in this novel are interesting (one of my favorites was Erin's nephew and his quest for license plates!), and there are several sub-plots that keep it interesting. I had not read any prior books in this series, so the constant reference to past events relating to Erin's father's death and her friend Kim, the sheriff's deputy, seemed confusing and distracting to me. It would be good for the author to explain these a bit more (for the novice reader) or minimize references to them. The main plotline was nicely constructed with enough twists and turns to keep it interesting. The descriptions of the town and its jazz festival made me wish I could visit. I would, however, like to see Erin's cats become a bit more involved in the story. I'm always frustrated when I see a cat on the cover and then they're no more than a brief mention here and there. In all, a fun read!

Erin Murphy the owner of Glacier Mercantile aka The Merc, is sponsoring the annual jazz festival and workshop at Jewel Bay Montana. During a concert, Erin notices some tension between Dave Barber and Gerry Martin, the local musician who became a star. Martin introduces Gabrielle Drake to the crowd as his discovery. He is in a bad mood after the concert and telling different people off left and right. What brought this on? Erin does not know. Then Gerry Martin is seen being pushed off a rock to his death by Erin's boy friend's friend while they were kayaking down the river. Now who would push Gerry to his death and why? The police investigate, and so does Erin. She finds out a lot of different secrets going on around town. So who really killed Gerry and why? You will need to read the book to find out. Oh, and bonus....great receipes at the end of the book! I received a copy of this book from Net Galley

Take an idyllic Montana town and fill it with music lovers, family members, and people just trying to get by, and then toss a music icon off a cliff and watch mayhem ensue. That's what happens here, and the result is an enjoyable read. The book is about 65% mystery, 25% romance, and 10% family relationships--a distribution I was quite happy with. I like Erin, and I had fun learning about her shop, her family, and her life. I also enjoyed meeting the various townspeople, though I felt like there were too many of them introduced to me as a new reader to the series. It was hard for me to keep everyone straight. And, because the victim was so unlikable and the reasons Erin felt she had to solve the murder were far-fetched, it didn't feel like all that much was at stake. That said, I'll be looking forward to spending more time with these folks in the next book in the series, and perhaps then it won't become as confusing for me.

Easy, breezy who-done-it. Nothing heavy or too involving. One of this novels you can put and pick up days later without missing a beat

Erin Murphy, manager of Murphy’s Mercantile (aka the Merc), is tuning up for Jewel Bay’s annual Jazz Festival. Between keeping the Merc’s shelves stocked with Montana’s tastiest local fare and hosting the festival’s kick-off concert, Erin has her hands full.

Discord erupts when jazz guitarist Gerry Martin is found dead on the rocks above the Jewel River. The one-time international sensation had fallen out of sync with festival organizers, students, and performers. Was his death an accident―or did someone even the score?

Despite the warning signs to not get involved, Erin investigates. And when the killer attacks, she orchestrates her efforts into one last crescendo, hoping to avoid a deadly finale.

This book was a complicated read with lots of characters that if you didn't bookmark the list of characters page, you might get lost. The saving grace is the supporting character in this book who I would read if he had his own book. I won't let anything slip with that character because I think it's worth reading just for his story alone. This book is suitable for ages 18 and over. Overall, at the end of the day this was a pleasant read but not extraordinary.

I was given a copy of this ARC from the publisher on Netgalley for a honest review. All of the above comments are my express opinions.
