The daughter of a New England heiress, seventeen-year-old Sam has tried hard to fulfill her father's dying wish: "Take care of your mother for me." Not an easy job. When her impulsive, romance-writing mom announces her engagement to a man whose last heiress wife died under suspicious circumstances, Sam tries to dissuade her mother. But her mom is convinced she'll finally have the "Happily Ever After" she writes about.
And then Sam's life implodes. Her mom's fiancé turns up dead, and a mountain of circumstantial evidence points to Sam as the killer. On trial for murder, she fights to prove her innocence with the help of her boyfriend's dad, an ex-homicide cop.

Just when things are looking especially bleak, Sam uncovers evidence she never expected to find. She faces a tough decision: At what point does the price of loyalty become too high?
