The friendship, magic, and laugh-out loud adventure continues in this hilarious chapter book series! Best friends Demelza and Nessa are always up for adventure. After all, what else is there to do on the sleepy island of Penfurzy? The two girls have discovered a magic world of myth and legend in a submerged castle just off the island, and now, accompanied by their pet goose Captain Honkers, are on a quest to help a headless knight (or rather, a knight who is JUST a head) find treasure. They set off on their bikes and explore both the everyday and legendary worlds, and encounter everything from a sullen bully named Connan to a ghost train to an ancient tomb beneath a shuttered amusement park. Along the way, the two girls will become braver and even closer friends.
