Fortunately, The Milk is a tale of what happens when Dad has been left in charge of his two children. When he goes out to buy the milk, the weird fun begins. He is abducted by globby, five-eyed aliens. He also meets pirates who have never heard of "walking the plank"; he befriends a talking dinosaur and meets a god named Splod.
The story is brought fantastically to life by Chris Riddell's inventive and witty caricature illustrations (Dad is a version of the younger Gaiman).
