From the legendary author of Hatchet, a laugh-out-loud middle-grade romp about a boy, his free-thinking dad, and the puppy-training pamphlet that turns their summer upside down. Twelve-year-old Carl is fed up with his father's single-minded pursuit of an off-the-grid existence. His dad may be brilliant, but dumpster-diving for food, scouring through trash for salvageable junk, and wearing clothes fully sourced from garage sales is getting old. Increasingly worried about what schoolmates and a certain girl at his new school might think of his circumstances—and encouraged by his off-kilter best friend—Carl adopts the principles set forth in a randomly discovered puppy-training pamphlet to “retrain” his dad’s mindset . . . a crackpot experiment that produces some very unintentional results. This is a fierce and funny novel about family and untangling some of the ties that bind from middle-grade master Gary Paulsen.
