It doesn�t take long for the police to realize a serial killer is on the loose�and that his spree has just begun. Detective Mackenzie White, young, tough, smarter than the aging, chauvinistic men on her local force, finds herself called in grudgingly to help solve it. As much as the other officers hate to admit it, they need her young, brilliant mind, which has already helped crack cold cases that had left them stumped. Yet even for Mackenzie this new case proves an impossible riddle, something the likes of which she�and the local force�have ever seen. With the FBI called in, together, an intense manhunt ensues. Mackenzie, reeling from her own dark past, her failed relationships, and her undeniable attraction to the new FBI agent, finds herself battling her own demons as her hunt for the killer takes her to the darkest places of her mind.In CAUSE TO KILL, Homicide Detective Avery Black has been through hell.

She lost her husband and her daughter, and her life fell apart around her. Trying to redeem herself, Avery has turned to the other side of the law. Working her way up the ranks, she has reached Homicide Detective, to the scorn of her fellow officers, who still remember what she did, and who will always hate her.Yet even they cannot deny Avery�s brilliant mind, and when a disturbing serial killer strikes fear into the heart of Boston, killing girls from elite colleges, it is Avery that they turn to. It is Avery�s chance to prove herself, to finally find the redemption she craves. And yet, as she is soon to find out, Avery has come up against a killer as brilliant and daring as she.In ONCE GONE, women are turning up dead in the rural outskirts of Virginia, killed in grotesque ways, and when the FBI is called in, they are stumped. A serial killer is out there, his frequency increasing, and they know there is only one agent good enough to crack this case: Special Agent Riley Paige. Riley is on paid leave herself, recovering from her encounter with her last serial killer, and, fragile as she is, the FBI is reluctant to tap her brilliant mind. Yet Riley, needing to battle her own demons, comes on board, and her hunt leads her through the disturbing subculture of doll collectors, into the homes of broken families, and into the darkest canals of the killer�s mind. As Riley peels back the layers, she realizes she is up against a killer more twisted than she could have imagined.In A TRACE OF DEATH, Keri Locke, Missing Persons Detective in the Homicide division of the LAPD, remains haunted by the abduction of her own daughter, years before, never found. Still obsessed with finding her, Keri buries her grief the only way she knows how: by throwing herself into the cases of missing persons in Los Angeles. A routine phone call from a worried mother of a high-schooler, only two hours missing, should be ignored. Yet something about the mother�s voice strikes a chord, and Keri decides to investigate. What she finds shocks her. The missing daughter�of a prominent senator�was hiding secrets no one knew. When all evidence points to a runaway, Keri is ordered off the case.
