Rent a Friend — Frieda Hughes

Poor Danny is lonely. Looks like he'll have to go out and find a companion! So he heads straight for the pet shop -- a nice little dog will suit him. But the pet shop owner doesn't have any dogs, and he offers Danny something else instead -- a living, breathing, "human" friend of his own. But perhaps making friends isn't quite that simple, as Danny begins to realize in the adventures that follow.
