The Lying Game
Book 1 in the The Lying Game Series · by Sara Shepard
Synopsis
Emma Paxton has spent her whole life in foster care. One night, she stumbles across a video online of a girl who looks exactly like her — a girl named Sutton Mercer who lives a glamorous life in Tucson, Arizona.
When Emma tracks Sutton down, her twin convinces her to step into her life for a few days. But then Sutton vanishes, and Emma is stuck pretending to be someone she is not.
The twist: Sutton is dead, and she narrates the story as a ghost, watching Emma try to solve her murder while living her life.
