Three friends and the totally fantastic bunker

A bunker is the most secretive hideout. Everyone needs one. George is almost eleven years old and he would love to own a gerbil. Or a dog. Or any other soft and cuddly animal he could play with when he comes home from school. But he is not allowed. Everything is an issue. And so George finds himself three friends and a bunker. Doctor, Miss and Agent, or otherwise known as a horse, a cat and a dog will soon teach George that if he wants anything, he needs to be patient, that the best place to think is in a tree and also that everything is not always as it seems. Thanks to his three friends, George realises that Laura is awesome, he solves a family mystery and he also gets better at maths.
