About this ebook

From the pen of Sir Terry Pratchett, beloved and bestselling author of the Discworld fantasy series, comes a reality-bending tale of virtual heroism that will leaves readers breathless from laughter, and suspense. 

The alien spaceship is in his sights. His finger is on the Fire button. Johnny Maxwell is about to set the new high score on the computer game Only You Can Save Mankind.

Suddenly:

We wish to talk.

The aliens aren't supposed to surrender -- they're supposed to die! Now what is Johnny going to do with a fleet of alien prisoners who know their rights under the international rules of war and are demanding safe-conduct? It's hard enough trying to save Mankind from the Galactic Hordes. It's even harder trying to save the Galactic Hordes from Mankind.

But it's just a game, isn't it? Isn't it...?
