Both Matt Coyle (author) and Travis Baldree (narrator) were new to me, and both are extremely talented. I loved the setting of this book being LaJolla California as I am somewhat familiar with the area. I found this listen to be thrilling and have amazing characters. I loved the unexpected twists and turns. This particular book is a standalone and yet part of a series. I was voluntarily provided with this review copy audiobook at no charge upon my request by the author, narrator, and/or publisher. My review is not a synopsis of the book, but rather my opinion of it. I do not believe in giving away spoilers in reviews.
