Desperate and three months behind on rent, Sera Voss takes a live-in nanny position at Caldwell House — a remote estate belonging to glacially cold tech billionaire Dominic Ashford, whose five-year-old daughter Wren hasn't been held by her father since the night her mother died. As Sera slowly draws Wren out of her silence and finds herself dangerously close to cracking open Dominic's iron composure too, she begins to notice things — details sewn into the very fabric of the house that don't add up about how Lydia Ashford really died. The more Sera uncovers, the harder it becomes to separate the man she's falling for from the secrets the house seems determined to keep. Because Caldwell House has been holding its breath for a long time — and Sera is starting to suspect she wasn't hired to help a little girl heal, but to stop asking the wrong questions. How do you protect a child from the truth about her father — when you're not sure you're safe from it yourself?
