What's done in darkness : a novel / Laura McHugh.

"On a hot, hazy summer day, Sarabeth is forced to work her family's farmstand in Arkansas. It was only recently that Sarabeth had a normal teenage life in town, able to see her friends, starting to date--but that was before her parents found God and moved her and her siblings to a farm in the middle of nowhere. Now she has to wear long dresses even in the blistering heat, can't cut her hair, and can't spend time with anyone her age. Sarabeth has become rebellious and wayward, refusing to adapt--then she is taken. Blindfolded and chained to a basement wall, Sarabeth is held captive for weeks by a person she never sees or speaks to, and just when she thinks her life is about to be over, she wakes up along the side of a highway, where she is discovered by a passing motorist. Now an adult, she goes by Sarah, has cut ties with her family entirely, and has made a contented, if solitary life for herself as an adult in St. Louis. That is, until Detective Nick Farrow with the Missouri Highway Patrol Missing Persons until calls her, wanting her help to investigate the recent disappearance of a young girl in a case which bears striking similarities to Sarah's own."-- Provided by publisher.
