Only Daughter by Anna was also left in my little free library. Amazon: “In 2003, sixteen-year-old Rebecca Winter disappeared. She’d been enjoying her summer break: working at a fast-food restaurant, crushing on an older boy and shoplifting with her best friend. Mysteriously ominous things began to happen—a presence in her room at night, periods of blackouts, a feeling of being watched—though Bec remained oblivious of what was to come. Eleven years later she is replaced. A young woman, desperate after being arrested, claims to be the decade-missing Bec.” This was a very quick and easy read and surprisingly good. I definitely did not predict the ending at all.
