Mark Walden spent ten years producing video games for a living before finally deciding that perhaps it was time to do some real work. With the bitter taste of rejection from the NASA astronaut training programme still in his mouth he decided (luckily) that maybe he should try and write a book instead. He is happily married (as is his wife, he hopes) and is the proud father of Megan. He is owned by Marge, his cat, who has provided invaluable assistance at every stage of the writing of both books.
