It leave you on a cliffhanger so there must be another book coming out! Okay so if you haven’t read any of the previous books in the series, the characters won’t matter much for you, and it will just be a story about people solving puzzles - which it mostly is. 

A friend who had read this said she did not feel as engaged because the primary characters are no longer Avery and the Hawthorne brothers but I actually found this book and the characters to be very engaging. I liked that there were multiple storylines some with new and some with familiar characters. I did feel like there should have been more to this book though, it felt like just half a book.
