Raised in a secluded island mansion deep in the woods and kept isolated by her true crime-obsessed parents, she has spent the last several years living on her own, but unable to move beyond her past—especially the disappearance of her twin brother Andy when they were sixteen. With her father’s death, Dahlia returns to the house she has avoided for years. But as the rest of the Lighthouse family arrives for the memorial, a gruesome discovery is made: buried in the reserved plot is another body—Andy’s, his skull split open with an ax. Each member of the family handles the revelation in unusual ways. Her brother Charlie pours his energy into creating a family memorial museum, highlighting their research into the lives of famous murder victims; her sister Tate forges ahead with her popular dioramas portraying crime scenes; and their mother affects a cheerfully domestic façade, becoming unrecognizable as the woman who performed murder reenactments for her children. As Dahlia grapples with her own grief and horror, she realizes that her eccentric family, and the mansion itself, may hold the answers to what happened to her twin.

    Hired by companies seeking trustworthy employees and by the lovelorn hoping to find happiness, Anna likes to keep the real mess of other people’s lives at arm’s length and on paper. But when she is called to use her expertise on a ransom note left behind at a murder scene in the small town she and her son have recently moved to, the crime inevitably gets under Anna’s skin. Was the child kidnapped from his home by his own mother, trying to save him from his abusive father? Thirteen years ago, Anna did the same thing for her unborn son, now a troubled teen rebelling against the protected life she’s given him.The local sheriff wants no part of Anna’s brand of hocus pocus, but he’ll do whatever it takes to bring his community and his office back under control. Anna is able to discern from the note that no one in the little boy’s family has been safe for a long time. And bringing him and his mother home could be the worst possible outcome for them.
