FBI Agent Rachel Gift, 33, unparalleled for her ability to enter the minds of serial killers, is a rising star in the Behavioral Crimes Unit—until a routine doctor visit reveals she has but a few months left to live. Not wishing to burden others with her pain, Rachel decides, agonizing as it is, not to tell anyone—not even her boss, her partner, her husband, or her seven-year-old daughter. She wants to go down fighting, and to take as many serial killers with her as she can. With a rash of people dying suspiciously from high bridges, jumping to their deaths in apparent suicides, the FBI is called in to investigate. On suspicion of a serial killer, Rachel is assigned the case, and soon realizes she is up against something more diabolical than she could have imagined. In an epic game of cat and mouse, can Rachel stay healthy enough to outsmart the killer and catch him before it’s too late? And can she keep her own demons—and her own traumatic past—at bay?
