Will Everett wasn’t born with a silver spoon in his mouth, but after his family’s fortunes change, he finds himself with a first-class ticket for The Boundless. The longest, most glamorous locomotive in the world, it stretches more than eleven kilometres long and pulls an astounding 987 cars: passenger cars, shooting galleries, gardens, an onboard swimming pool, cinema and much more. But its maiden voyage won’t be a smooth ride for Will. After witnessing a murder during a station stop, he barely makes it back onto the train (with a running leap!), then must work his way from the caboose forward to his father in first class—with the murderer and his cronies on his tail. Luckily, a clever and nimble friend is perfecting her act in The Boundless’s circus car, and there the real thrill ride begins. Sasquatches, bog-dwelling hags and illusions abound in this outsized middle-grade adventure.
