Urchin Beach isn't the sort of place where bad things happen. The little seaside town is too lucky for that. But then one day, a thief steals something precious--the town's dragonfly staff, which is the source of all its good fortune and the most important part of the upcoming Dragonfly Day Festival. Amelia MacGuffin is no detective. She's eleven, quiet, and unlike her four younger siblings, she has no special talents. But Amelia loves her town. Her family has lived there forever. Her parents run the Pacific General Store, and she and her best friends Birdie and Delphine are about to start middle school. If Amelia doesn't find the staff, the Dragonfly Day Festival will be cancelled. The town needs that tourist money to survive. Unless she cracks the case, Amelia's family will lose everything--including the adorable stray dog they've fallen in love with.
