Jonny lives with his mom on the hardscrabble coast of North Carolina. The old coast is underwater -- Jonny's dad makes a living diving to salvage valuables from drowned towns, rarely home. It's a hard life. When Jonny rescues Kitty Itty he learns a bit about responsibility and caring, but the coming hurricane Xerxes may teach them both some harder lessons.
