In the coastal village of Maiden Rock, Maine, Quinnie Boyd's teacher has disappeared. Quinnie thinks it's a kidnapping case, but her mom, the town sheriff just thinks the teacher has left town. Still, Quinnie's going to follow her instincts that something's wrong. Her investigation will take her through a damp and smelly marsh, a lobster pound, and some of Maine's messiest places. She'll even get help from her glamourous new neighbor, Mariella. As the girls hunt for clues, they'll encounter a swarm of cats, two nuns with a speeding habit, and a group of tattooed rocker-types. But will they find Quinnie's teacher?
