Twelve-year-old Abigail O’Keefe is AO’K. At least that’s what she tells herself when she realizes the lifeboat she was hiding in has somehow detached itself from the cruise ship, and she’s floating alone in the ocean. She wonders if this has anything to do with the ball of light she followed while playing hide-and-seek with her friends.
After running ashore on a strange land and meeting the Easter Bunny, she learns she’s on Holiday Isle. It’s a magical island ruled by four saints: Saint Nick in the North, Saint Valentine in the West, Saint David in the East, and Saint Patrick in the South. But St. David, the red dragon, is missing, and the island is in an uproar. As much as Easter would like to help Abigail get home, he’s found himself on the Naughty List. And take it from him, Abigail does not want to be on the Naughty List. Because if you get caught by the Toy Soldiers who manage the list, you’ll serve hard time in the North Coal, a hard labor coal mining camp enforced by Krampus, an imp who’s the polar opposite of Santa.
Easter advises Abigail to seek the help of St. Patrick but steer clear of the Pumpkin Patch, which is home to Hauntra–the Queen of Halloween. And whatever Abigail does, don’t let anyone know about the daffodil she’s wearing in her hair. During her quest to get home she meets many Holiday Mascots: April Fool, Mardi Gras, Cinco and his sister De Mayo, Bones, and many others, including Jack Frost! But who can she trust? Certainly not the scarecrow who’s already lied to her about the Tooth Fairy. Can she believe St. Patrick? Chuck the Groundhog doesn’t think so. He wouldn’t trust a leprechaun any farther than he can throw one. Not to mention, St. Patrick wants her to steal Dreidel’s Time Top–a magical item that can turn back time by eight minutes. A task so daunting, it’s sure to get her locked away forever in the North Coal.
