Fox has released images and an official synopsis for this week's episode of The Simpsons, which features a guest appearance by Neil Gaiman. In addition, Gaiman posted a clip from the show which, as you can see from the above screenshot, includes a glimpse of a bookstore display showcasing the author's work, including The Absolute Sandman, Vol. 1, and The Absolute Death. Clearly they're not in the Springfield Barnes & Noble.
Here's how Fox describes the episode, called "The Book Job": "Lisa becomes disheartened when she learns the shocking truth behind the 'tween lit' industry and her beloved fantasy novel characters. But Homer decides to cash in on the craze and forms a team to group-write the next 'tween lit' hit, with the king of fantasy, Neil Gaiman (guest-voicing as himself), lending his expertise to the effort. After catching the eye of a slick industry publisher (guest-voice Andy Garcia) at the Springfield Book Fair, the team gets an advanced copy of their work and discovers that the corporate lit business is a bigger operation than they imagined."
Gaiman previously appeared in animated for in a 2010 episode of Arthur. Check out the clip and images from "The Book Job" below. The Simpsons airs Sunday at 8 p.m. ET/PT on Fox.
