iZombie Vol. 1: Dead to the World by Chris Roberson. Gwen is a zombie, but it's not too bad--as long as she eats one brain a month, she passes for human & avoids becoming a mindless monster, & her gravedigging job keeps her supplied. But when she eats a brain, she absorbs its memories, and her latest meal shows her an unsolved murder. Gwen & her friends, ghost-girl Ellie & were-terrier Scott, set out to solve this murder in this Halloweenishly fun B-movie-style paranormal mystery.
