The Taking of Planet 5 is the twenty-eighth book in the ridiculously long—but still, not long enough—series known as the Eighth Doctor Adventures (but probably not the ones you were expecting...), written by two irrelevant pretty cool guys called Simon "Butcher"-Jones, and Mark "The Clap"-ham. Contrary to popular belief, nobody in the book ever actually visits Planet 5, nor does anyone technically take it. You could probably sue for false advertising, or something.
