Shadow Game (GhostWalkers, Book 1)

#1 New York Times bestselling author Christine Feehan plunges readers into the darkest recesses of the mind as a man and a woman discover the terrifying power—and the forbidden passion—that could destroy them both in the first novel in the GhostWalker series.
 
The brainchild of renowned scientist Peter Whitney and his brilliant daughter, Lily, the GhostWalker experiment was created to enhance the psychic abilities of an elite squadron, transforming their natural telekenetic powers into a unique military weapon. But something has gone wrong...
 
In the isolated underground, the men have been dying, victims of bizarre accidents. Captain Ryland Miller knows he is next. When Dr. Whitney himself is murdered, Ryland has only one person left to trust: the beautiful Lily. Possessed of an uncanny sixth sense herself, Lily shares Ryland’s every new fear, every betrayal, every growing suspicion, and every passionate beat of the heart. 
 
Together, they will be drawn deeper into the labyrinth of her father’s past...and closer to a secret that someone would kill to keep hidden.
