Celebrated author and poet Margaret Atwood will collaborate with "Sheltered" artist Johnnie Christmas on a graphic novel trilogy to debut next fall from Dark Horse Comics.

The New York Times describes "Angel Catbird" as an all-ages story about a superhero who draws his powers from two animals. "Due to some spilled genetic Super-Splicer, our hero got tangled up with both a cat and an owl," Atwood explained in a statement, "hence his fur and feathers, and his identity problems."

Best known for her 1985 novel "The Handmaid's Tale," which won the Arthur C. Clarke Award, Atwood has also published short stories, nonfiction and children's literature.

An environmental activist, Atwood will use "Angel Catbird" to help raise awareness for Nature Canada's Keep Cats Safe and Save Bird Lives.
