Sibling stowaways take a supernatural safari through Victorian England. Though Kenneth and Candace are twins, they couldn't be more opposite. Even so, the one thing they do share is a fascination with their eccentric Uncle Nigel, the "creature catcher." He works for the Londinium Zoo, collecting fantastic beasts like unicorns and fire-belching salamanders. When the London Times announces a creature-catching contest for kids, the twins hatch a plan to win. As Uncle Nigel heads for the Moorlands to capture a will-o'-the-wisp, Kenneth and Candace stow away on his dirigible, determined to bring back a troll and a pixie. But neither of the creatures is what they'd expected, and the catchers find themselves caught. Soon the twins have rescued each other, befriended a troll and raced against time to save Uncle Nigel. Their triumphant return to Londinium with their uncle and their trollish friend wins them the prize and recognition as creature catchers of the highest order. Full of fun and adventure, Creature Catchers evokes a wonderful world of mythological beings.
