I don't know what your terms are, but can we submit Witches and Bandits and Swords (Oh My)? The ebook version was short-listed for the Big Al's Books and Pals Readers' Choice Award, and that's largely what inspired me to start making video games.
Ironically, the video game is free, but the ebook version costs 99 pence. In case anyone's wondering, this is due to the licensing terms for our graphics...
