Torn to Pieces — Margot McDonnell

SEVENTEEN-YEAR-OLD ANNE ALWAYS thought her mother was kind of quirky. In fact, her mom's taste in 70s-esque furniture and mysterious frequent business trips were just the tip of the quirky iceberg. When her
mom doesn't come home on time from one of her long jaunts, Anne isn't too surprised. But when a day late turns into a few days late, Anne knows something is very wrong.

She tries the hotel number that her mother left her, but it has been disconnected. Then a strange man keeps leaving messages on their answering machine, looking for a woman who doesn't even live there. However, when Anne discovers a lengthy letter from her mother explaining why she has disappeared, the fabric of Anne's relatively normal life is torn to pieces. Despite her shock, Anne must pull herself together and protect herself--from people who want to find and hurt her mother, and the strange new boy who may change everything.
