A Killing Cold

An amnesiac grows suspicious of her new fiancé’s family in this taut psychological thriller from Marshall (No One Can Know). Within months of meeting handsome scion Connor Dalton at a party, Theodora “Theo” Scott—who has significant gaps in her memory of the early years of her life—eagerly accepts his marriage proposal. As the novel opens, Theo is preparing to accompany Connor to his family’s vast, isolated winter estate, even as she fears that his relatives suspect her of gold-digging. Those anxieties spike when Theo receives a series of anonymous text messages just before they arrive, the eeriest of them asserting that the sender knows who Theo is and “what [she] did,” and will expose her secrets if she doesn’t keep away from Connor. Once Theo settles in at the Daltons’ estate, she attempts to suss out who’s been threatening her, while also contending with an eerie feeling that she’s been on the property before. Flashbacks gradually fill in the blurry details of Theo’s past, keeping readers on edge. Fans of Riley Sager will enjoy this. Agent: Lauren Spieller, Folio Literary. (Feb.)
