Meet Oona. The big sea’s littlest mischief maker. She and her best friend, Otto, love to search for treasure . . . but often find trouble instead. Messy trouble. Tricky trouble. Even shark-related trouble. That’s never stopped them before, though! After all, no proper treasure hunt is without some adventure. But when the grandest treasure yet is stuck in a deep, dark rift, Oona’s not sure if she can dive right in. What might be waiting for her in those unknown waters?
Author

Kelly is the award-winning author of several children’s books, thousands of To-Do lists, and a few recipe cards. Two of her books, Grace For President and The Sandwich Swap, were New York Times bestsellers. Like most kids who grew up in the 1970’s, Kelly had a pet goat and bought all her clothes from the Sears catalog. Like most teenagers who grew up in the 1980’s, Kelly had really big glasses and feathered hair. Today, Kelly lives with her husband and three children in southeastern Michigan, where she enjoys writing just about everything except her own bio.
