What does Danny Dragonbreath do when his super-annoying cousin Spencer gets kidnapped by knights? First, he thinks about how nice and quiet Thanksgiving would be without Spencer. Then, of course, Danny goes off to rescue him, with his cohorts Wendell and Christiana by his side. Their action-packed mission involves a dirty dungeon, a very squelchy moat, a big surprise for Christiana, and jousting galore.
