I finally got to read this book and I am so glad that I did. The beginning started a little slow for me but once I got a third of the way into the book it really picked up. When we start that book we learn that Matt Pine's family was killed by a gas leak while on vacation in Mexico, leaving his only remaining family his older brother who is in jail for murder. There are multiple points of view in this book and the two main ones are from Matt Pine and FBI Agent Sarah Keller. The FBI gets involved because while they think the deaths are from a gas leak there is also some details that make them think there might be more to their deaths. There were times that I found this book difficult to read because we are getting points of view from the deceased family members and that made me pretty emotional. This was a great thriller and the ending got me and I did not see the ending coming. I can't wait to read more from this author and I hope we get more books that follow Sarah Keller. Highly recommend this one. Thank you Minotaur and Goodreads for my copy!
