I wish you could change dads, the way you can change library books. I wish there was a Dad Library.

Joseph is fed up with his dad. He forgets to go shopping, he cooks terrible meals, he doesn''t help Joseph with his homework and he makes him eat school dinners.

Then Joseph discovers the Dad Library, crammed full with all sorts of wonderful dads. Should he borrow an Organizer Dad, or a Sporting Dad, or a Clever Dad, or an Indulgent Dad? Joseph wants to try them all. But which one will he want to keep?
