Meet Hex – the unluckiest alien in the universe! Everything he tries to do goes wrong. He can’t shoot a ray gun, he can’t fly a spaceship, and he couldn’t spot an earthling if it jumped up and bit him on the probe! He’s easily the worst space invader on Planet X. So when Hex discovers that his long-lost father is living on Planet Earth, it seems like a chance for a fresh start – until he discovers that Earth is about to be invaded! How on earth can one small and unfortunate alien save the Earth – and his dad?
