Grant and Christina can't wait to visit Colonial Williamsburg with their mystery-writing grandmother Mimi and cowboy-pilot grandfather Papa. "It feels like you are whisked back in time when you go to Williamsburg!" says Mimi. And as soon as the kids arrive, they're whisked into a quirky colonial mystery involving a valuable-and missing-map! It's a gift for the Queen of England-but where is it? Join Grant and Christina as they tour some taverns, carouse in the Capitol, take a wild carriage ride, and even end up in 'gool'-all in the name of the Queen! It's a map mix-up you don't want to miss! Each mystery incorporates history, geography, culture and cliffhanger chapters that keep kids begging for more! Each mystery includes SAT words, educational facts, fun and humor, built-in book club and activities. Each Carole Marsh Mystery also has an Accelerated Reader quiz, a Lexile Level, and a Fountas & Pinnell guided reading level.
