It's down to Bob to save the world . . . All he needs is time!

Bob and his best friend Malcolm are determined to win the school talent competition with their band The Tentacles of Time. For one thing, there's £50 worth of vouchers to be won. For another, the future of the world depends on it.

Bob doesn't know why he can time travel. He does know that it always happens at the worst possible moments. Like when he's in the bath. Awkward! But when Bob comes face to face with his future self in the middle of a disastrous alternative reality, he has to do something!

In this terrifying version of the future, an evil genius has created a smile-operated selfie camera that turns people into zombies. The world as Bob knows it has completely collapsed. There's not even anywhere to get a decent pizza! It's up to Bob to fix the present, change the course of time and save the whole world!

A hair-raising race into the future and back again . . . and again.
