In this story Riley will have to face serious problems with her family. Her opponent is extremely intelligent, narcissist, with excellent planing and detail oriented skills and he'll kidnap her daughter Jilly and later on her partner Bill just to watch her suffer. He know how she thinks and acts but what he doesn't take into account is her capacity of making things happening and getting help from unexpected sources. Interesting and entertaining story!
I thank Ms. Pierce for this ARC.

Once Vanished - a review by Rosemary Kenny.
Once Vanished is an edge-of-your-seat spine-chiller by Blake Pierce, in his Riley Page series. The FBI profiler and her partner Bill are put in a cat-and-mouse situation, after Riley's adopted daughter Jilly is kidnapped by a sadistic killer who knows how to push their buttons.
A trail of past cases and psychological profiling leads to a thrilling denouement, in which Riley must make a life-or-death choice. Can she save both victims - or does she once more have to live with the guilt of failure?
