The books I ordered!

"Only You Can Save Mankind", "Johnny and the Dead", "Johnny and the Bomb"

Twelve-year-old Johnny receives a pirate edition of the new video game Only You Can Save Mankind from his friend Wobbler. However, he hasn't been playing for long when the ScreeWee Empire surrenders to him. After accepting the surrender he finds himself inside the game in his dreams, where he must deal with the suspicious Gunnery Officer as well as the understanding Captain, and work out exactly what they're all supposed to do now.

This might all be the result of an over-active imagination except that the ScreeWee have disappeared altogether from everyone else's copy of the game. With the help of another player, Kirsty, who calls herself "Sigourney" (as in Weaver), Johnny must try to get the ScreeWee home.

Terry Pratchett sold his first story when he was thirteen, which earned him enough money to buy a second-hand typewriter. His first novel, a humorous fantasy entitled The Carpet People, appeared in 1971 from the publisher Colin Smythe. Terry worked for many years as a journalist and press officer, writing in his spare time and publishing a number of novels, including his first Discworld novel, The Color of Magic, in 1983. In 1987 he turned to writing full time, and has not looked back since. To date there are a total of 36 books in the Discworld series, of which four (so far) are written for children. The first of these, The Amazing Maurice and His Educated Rodents, won the Carnegie Medal. A non-Discworld book, Good Omens, his 1990 collaboration with Neil Gaiman, has been a longtime bestseller, and was reissued in hardcover by William Morrow in early 2006 (it is also available as a mass market paperback (Harper Torch, 2006) and trade paperback (Harper Paperbacks, 2006). Terry's latest book, Making Money, was published in September 2007 and was an instant New York Times and London Times bestseller. In 2008, Harper Children's will publish Terry's new standalone non-Discworld YA novel, Nation.
Regarded as one of the most significant contemporary English-language satirists, Pratchett has won numerous literary awards, was named an Officer of the British Empire “for services to literature” in 1998, and has received four honorary doctorates from the Universities of Warwick, Portsmouth, Bath, and Bristol. His acclaimed novels have sold more than 45 million copies (give or take a few) and have been translated into 33 languages.
Terry Pratchett lives in England with his family, and spends too much time at his word processor.
