Oona and her best friend Otto love to search for treasure…and often find trouble instead.
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?
