by Casey Hill

Reilly Steel returns in a gripping new chapter of the USA Today bestselling forensic mystery series.

Former GFU investigator Reilly Steel is back in Florida to join her former mentor, legendary ex-FBI profiler Daniel Forrest, at his private behavioral analysis consultancy.

But before she can settle into her new role, a frantic call pulls them both into a brand new a family held hostage in their beachfront home by an unidentified captor who communicates through a series of complex riddles and psychological trials. As the crisis deepens, and the hostage-taker begins broadcasting the family’s torment online, Daniel must call on his wealth of behavioural insight to stay ahead of a mind that appears to anticipate every move.

With his son, Todd taking command of the police response, personal fault lines quickly begin to fracture under pressure. Old wounds resurface, loyalties are tested and all too soon, the profiler becomes the profiled.

Until Daniel is faced with the ultimate choice; in order to save the hostages - and his own son - the famed profiler must face the one mind he never managed to his own.

I really enjoyed the other books in the series and was excited to read this one to see what Riley and the rest of the gang were up to. However, I found it a bit of a slog at times and felt it was quite different from the rest of the series.

not as good as the rest of the series

I was excited to see a new Riley Steel book as I really enjoyed reading the earlier books. However I was a bit disappointed in this one. I missed the charm of Dublin. I did not like the relationship story with Chris. I understand they had a lot to adjust to. But there needs to be some positive signs especially since they were staying in the same bed. The kidnapping plot was good but hard to follow. I found myself re-reading sections just to try and understand the psychological verbiage.

3.5 stars. I was so surprised that a new book in this series was released that I forgot I said I wouldn't continue reading if it were to go on. It was an interesting reset (if that's what it was), I guess, we'll have to see.
