First of all, Scott Westerfeld has written a hilarious bonus chapter for his brilliant Leviathan series. Better yet, Keith Thompson has created an all new illustration to accompany it. Read it here while you await the release of their book of illustrations (The Manual of Aeronautics) next year. Do make sure you’ve read the series first, however.
Fans of The Chronicles of Narnia will also be thrilled to learn that C.S. Lewis’ estate has allowed the release of free audio files of the seven novels. You can download them here.
