Pandora's Game
By Jim Shepard, 2001

"Neil Joshua Carpenter and his friend, Mark Hudson, decide to create a comic book series about a vampire, Alistaire Bachman, a werewolf, Sean Mallory and a zombie, Trey Matthews. During the creation of the series, Neil uses hypnosis to get into his character's mind and release his own creativity. But something goes terribly wrong." (from Amazon.com)
