Everyone in Ashford, Cornwall, knows Meg Nichols, who selflessly cares for her invalid daughter, Grace. So when Meg is found brutally bludgeoned in her bed and her daughter missing, the community is rocked, and it appears that her unstable ex has come for revenge. Local journalist Jon Katrin had written an article about them that made him very unpopular, but he wants to atone for it by helping to find Grace. The Nichols' neighbor, Cara—contending with her own guilt over not being a better friend to Grace—becomes an unexpected ally, but in searching for the missing girl, Jon and Cara uncover answers more twisted than anyone could have ever imagined.
