The farm, with its unique animals—dragons, unicorns, and water snakes—is under threat. It's not just the omnipresent security measures that reveal this: fences, surveillance cameras, and even dangerous new creatures are in play. When Uncle Gideon also disappears without a trace, Tyler and Lucinda are left to fend for themselves in protecting the farm and all its animals. But what is the shady housekeeper Miss Needle planning? Is she a dangerous witch, as Tyler and Lucinda fear? An exciting reading adventure from the first page to the last.
