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.
An intensely gripping, psychological cat-and- mouse game is played out between FBI Special Agent Riley Page and Leo, (once her student) after he kidnaps her adopted daughter Jilly from her and partner Bill's home.
Unbelievable tension is ratcheted up scene by scene, as recreated face-offs from Riley's past play havoc with her mind, and she 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? Get a copy of Once Vanished today, to find out - and be prepared to read all night!
