From the living legend and award-winning author of Hatchet comes a laugh-out-loud eco-adventure 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 dad; he may be brilliant, but bin-diving for food, scouring through rubbish for 'salvageable' junk and wearing clothes fully sourced from garage sales is getting old. Increasingly worried by what his schoolmates will think – and encouraged by his riotous best friend – Carl decides to use a puppy-training pamphlet to 'retrain' his dad’s mindset . . . a crackpot experiment that produces some hilarious results! How To Train Your Dad is a fierce and funny novel about family, friendship and green-living from middle-grade master Gary Paulsen.
