Andy and Terry live in a tree house so fantastic it caters for every whim – as long as you're a primary school-aged boy, that is. There's swimming on one level, bowling on another, as much marshmallow as you could eat and all the gadgets and gizmos their brilliant imaginations could come up with. But this idyllic life also comes with responsibilities – one moment you're painting a cat yellow to see if it becomes a canary and flies away (no spoiler – it does), the next you get reminded of an overdue deadline to write a book. What on earth could possibly happen to inspire such a book overnight?
