My interest in tracking down the artists that have done covers for my books was recently rewarded when I met up with L. Autumn Andrews (and her invisible sister K. Angel) who did the cover for Extreme Makeover. I have another artist-autographed book for my shelf and a photo for my blog. L and K make up Autumn-Angel Art (click on the link for their Facebook gallery). Their twitter stream is here.
They are going a wide variety of game development, artwork and music, and I hear they have an iPhone app in the works. You’ll see more of their work in the next novel Bearing Northeast, since I had them create the twitter icons for my characters. See here for the tweets done by the characters as the novel was being written.
