Twenty years ago, Melanie Stokes was abandoned in a Boston hospital, then adopted by a wealthy young couple. Gifted with loving parents, a doting brother, and an indulgent uncle, Melanie has always considered herself lucky. Until the first cryptic, threatening note arrives: “You Get What You Deserve.” Melanie has no memory of her life before the adoption. Now someone wants her to remember it all - even the darkest nightmare the Stokes family ever faced: the murder of their first daughter.

A serial killer watches and waits. Each time, he takes two victims, preparing the first's body with all the clues the police need to find the second, who is still alive. The clock ticks, and the second one can still be saved. But the police never make it in time. The second one dies. For years, the killer has plagued the city with the same pattern, but the police never pick up on it quickly enough.

For ex-FBI profiler Pierce Quincy, it's the beginning of his worst nightmare: a car abandoned on a desolate stretch of Oregon highway, engine running, purse on the driver's seat. And his estranged wife, Rainie Conner, gone, leaving no clue to her fate.

A man is dead, shot three times in his home office. But his computer has been shot twelve times, and when the cops arrive, his pregnant wife is holding the gun. D. D. Warren arrives on the scene and recognizes the woman - Evie Carter - from a case many years back. Evie's father was killed in a shooting that was ruled an accident. But for D.D., two coincidental murders is too many. Flora Dane sees the murder of Conrad Carter on the TV news and immediately knows his face. She remembers a night when she was still a victim - a hostage - and her captor knew this man.

For Kimberly Quincy, FBI Special Agent, it all starts with a pregnant hooker. The story Delilah Rose tells Kimberly about her johns is too horrifying to be true; but prostitutes are disappearing, one by one, with no explanation, and no one but Kimberly seems to care.

What do you do when a killer targets the people you love the most? When he knows how to make them vulnerable? When he knows the same about you? These are the questions that haunt FBI Special Agent Pierce Quincy. The police say his daughter’s death was an accident. Quincy will risk everything to learn the truth - and there’s only one person willing to help. Ex-cop Rainie Connor had once been paired professionally - and personally - with the brilliant FBI profiler. He helped her through the darkest days of her life.

One question, a split-second decision, and Brian Darby lies dead on the kitchen floor. His wife, state police trooper Tessa Leoni, claims to have shot him in self-defense, and bears the bruises to back up her tale. For veteran detective D. D. Warren it should be an open-and-shut case. But where is their six-year-old daughter? As the homicide investigation ratchets into a frantic statewide search for a missing child, D. D. Warren must partner with former lover Bobby Dodge to break through the blue wall of police brotherhood, seeking to understand the inner workings of a trooper’s mind while also unearthing family secrets.

Justin and Libby Denbe have the kind of life you’d find in the pages of a glossy magazine: A beautiful 14-year-old daughter. A gorgeous brownstone on a tree-lined street in Boston’s Back Bay neighborhood. A great marriage, admired by all. A perfect life. When investigator Tessa Leone arrives at the crime scene in the foyer of the Denbes’ home, she finds scuff marks on the floor and a million tiny pieces of bright green Taser confetti. The family appears to have been abducted.

Eight years ago, Sharlah May Nash's older brother beat their drunken father to death with a baseball bat in order to save both of their lives. Now thirteen years old, Sharlah has finally moved on. About to be adopted by retired FBI profiler Pierce Quincy, and his partner, Rainie Conner, Sharlah loves one thing best about her new family: they are all experts on monsters.

It was a case that haunts Bobby Dodge to this day - the case that nearly killed him and changed his life forever. Now, in an underground chamber on the grounds of an abandoned Massachusetts mental hospital, the gruesome discovery of six mummified corpses resurrects his worst nightmare: the return of a killer he thought dead and buried.  

It was a case guaranteed to spark a media feeding frenzy: a young mother, blond and pretty, disappears without a trace from her South Boston home, leaving behind her four-year-old daughter as the only witness and her handsome, secretive husband as the prime suspect. But from the moment Detective Sergeant D. D. Warren arrives at the Joneses - a snug little bungalow, she senses something off about the picture of wholesome normality the couple worked so hard to create.

The last thing Boston Detective D. D. Warren remembers is walking the crime scene after dark. Then, a creaking floorboard, a low voice crooning in her ear... She is later told she managed to discharge her weapon three times. All she knows is that she is seriously injured, unable to move her left arm, unable to return to work....

Nicole Frank shouldn't have been able to survive the car accident, much less crawl up the steep ravine. Not in the dark, not in the rain, not with her injuries. But one thought allows her to defy the odds and flag down help: Vero.

FBI Special Agent Kimberly Quincy and Sergeant Detective D. D. Warren have built a task force to follow the digital bread crumbs left behind by deceased serial kidnapper Jacob Ness. When a disturbing piece of evidence is discovered in the hills of Georgia, they bring Flora Dane and true-crime savant Keith Edgar to a small town where something seems to be deeply wrong.  

The home of a family of five is now a crime scene: four of them savagely murdered, one - a sixteen-year-old girl - missing. Was she lucky to have escaped? Or is her absence evidence of something sinister? Detective D. D. Warren is on the case - but so is survivor-turned-avenger Flora Dane. Seeking different types of justice, they must make sense of the clues left behind by a young woman who, whether as victim or suspect, is silently pleading, Look for me.
