Blind for the first twenty years of her life, Kendra Michaels honed her other senses to almost superhuman perfection?and unintentionally became a secret weapon for the FBI. Her uncanny ability to pick up the most subtle audio, olfactory, and tactile cues in the world around her made her a law-enforcement legend. Today, her expertise is called for once again. When Kendra is approached by a dubious source about a serial murder investigation, her instincts tell her to steer clear. This time, however, the case is personal: The next name to turn up on the killer's hit list is Kendra's own ex-lover, an FBI agent who disappeared without a trace. Now it's up to Kendra to pick up the trail?or close her eyes again…forever.
