Who do you trust when you can't trust yourself? Having discovered who was behind her abduction, Samantha Campbell is still haunted by what happened. Memory lapses and a nagging suspicion that the cabin was only the beginning means Sam needs answers. Her only problem? The one person who might have them still wants to kill her. With Mack unwilling to forgive himself, and Blake refusing to let her anywhere near his brother, she must find other ways to piece together her missing time line. Hoping that returning to Tonbo's Islands will help, Blake and Sam are horrified to learn Kory's treachery runs even deeper. Ancients are missing, Kate's disappeared, and the worst part is Sam feels she may be responsible. She's willing to try almost anything to know what her other half has been up to, but with each new discovery, she slips deeper into something she may not be able to recover from. Driven by the need to set things right, she's thrown into a web of lies where she realizes she can't trust anyone, least of all herself.
