Archie McBudge was planning a sweet summer at Honeystone Hall. Picnics by the loch, watching the honeydragons flying around the hillsides, chasing ghosts through the shadowy castle hallways, and of course, testing out all the new sweets from the McBudge Confectionery Factory. But now the Wyrdie Tree, source of all the magic in the town of Dundoodle, is dying, and the guardian must save it before Dundoodle's magic is gone for good. And who's the guardian, you ask? That's right, Archie McBudge. With enemies on every side, puzzles to solve and secrets to uncover - not to mention a very scary dentist to avoid - Archie's summer's looking less like a strawberry marshmallow dream and more like a super-sour sherbet lemon with exploding bits that make your mouth go numb for a week!
