"Nora and Sophie Linden may be sisters, but they haven't been friends since the party last month. The night Sophie's boyfriend, Garrett, disappeared. Half the town thinks Garrett is dead, the other half believes he ran away, but Sophie knows something no one else does: Garrett left that party with Nora. Then Sophie starts receiving messages from someone who claims to be Garrett, promising revenge for what happened to him that night-- and for the lies both girls told to the police about it. Now Nora and Sophie must either trust each other again-- or risk their secrets leading them to their graves." -- Adapted from jacket.
