Life in school can be hard. It can be even harder when you're an alien spy sent to Earth to discover what the planet is like before the invasion fleet arrives. And it's even harder than that when you're quite short and your Earthling disguise makes you look like a ten-year-old... Join Ally N. Invasion in his quest to uncover the secrets of English lessons, P.E., D.T., P.S.H.E. and lots of other letters. Along the way, he'll make friends and mistakes - and a rather nice model of a rocket. But what will he do when seventy-five giant alien spaceships arrive, just after home time...? "I wrote this book as a tribute to all of the fantastic children I've taught over the years. Many of them were the inspiration behind the characters," says author Steve, whose novel will be enjoyed by seven- to eleven-year-old fans of science-fiction and humorous stories. Other than his previous students, Steve has also taken inspiration from Andy Stanton's `Mr. Gum' series and the works of Spike Milligan. The book is beautifully illustrated throughout in black and white.
