Abigail Gibson is gone. The morning after Christmas Day, she walks out of her home in the leafy suburbs of Westchester, New York, leaving behind a strange note on the kitchen table… and her ten-year-old son, Sam.
When her sister Gillian gets the call, she can barely believe it. Abigail has always been a little, well, unreliable, but she hasn’t done anything like this in a decade--not since Sam was born.
Now Gillian’s left taking care of Sam while she waits for news of Abigail’s whereabouts. But things aren’t so great in Gillian’s home either, where her husband’s odd behavior and late nights out are giving her doubts she thought she'd never have.
Meanwhile as Abigail shows no signs of re-appearing, Gillian is forced to confront the two big questions: what secrets is her sister hiding…and is she ever coming back?
The answers will upend her world...
