When a four-year-old girl disappears the night after her birthday party, all the guests are suspects. Except for the one who turned up dead. Mary Kubica meets Lisa Jewell in this dark and twisty mystery of domestic suspense.

Summer Brownley is barely holding it together. Her marriage is ending and her heart is in pieces, but she still threw a damn good party. Afterward, though she really shouldn’t, she curls up with a bottle of wine. It’s her soon-to-be ex-husband’s night with the kids, what could go wrong?

Except everything.

The FBI arrives at dawn. Her four-year-old daughter is missing. But the kidnapping is just the beginning of her nightmare. Because as the search for her daughter begins, one of her party guests turns up dead.

FBI Agent Willow Thorne is on the trail.

There is no shortage of suspects: the cheating ex-husband, a best friend with regrets, a covetous surrogate. Every new lead uncovers another lie. Thorne has a knack for noticing what people choose not to tell her, but there’s something about this case that has her second-guessing herself.

If Summer wants to help Thorne find the kidnapper, she’s going to have to expose her most tightly held secrets.

Before her daughter is gone for good.
