Three Times Lucky by Sheila Turnage

Three Times Lucky is one Philip Marlowe away from being a full-fledged crime noir for young readers. Miss Mo LoBeau is a quick tongued, rising sixth grade orphan living in tiny modern-day southern town, Tupelo Landing, with her adopted parents, The Colonel and Miss Lana, who own and operate a cafe attached to their home. When big-city Detective Starr comes to Tupelo investigating a murder, secrets about everyone's past begin to surface, and Mo and her best friend Dale race against time to solve the mystery and save the only family Mo has ever known.

This debut novel from Sheila Turnage is packed with humor, deception, wit, and colorful characters, and it's buzzing on many year-end must-read lists.
