Maggie has everything her sister Rose always wanted. A handsome husband and two adorable children, Emily and Elliot. But what Rose doesn't see is that Maggie is struggling.

When Maggie finally cracks, walking out one day and not returning, Rose is right there to step into the breach . . . You trust your sister to look after your children. But should you?
