They Are Back! by David M cameron

When the fate of the world is in your hands and you are thirteen years old, you need all the help you can get. The problem is when your support team comprises a teen girl, an older bully and your pet dog, you know you are in trouble.

Can Christopher defeat Mr Smith and his vanguard of alien reptilian invaders? How do you know your enemy, when they can change their shapes to become anyone or anything? Is anyone safe?

A quiet seaside town becomes the centre of a world alien invasion, where no one is safe and nothing is as it seems.
