This is not a comic book that will ever exist.
My latest children's book in progress--Dragonbreath 2, slated for publication by Penguin Dial in Spring 2010--had a throwaway line about the hero reading a comic series called "Empire of Feathers" which is described as being "about an alternate universe where birds ruled the world, and it was dark and gritty and had lots of battle scenes and intrigue and poisonings and magic, and a clan of rooster assassins that wore cloaks made of their victim's feathers."
I have no time to do such a comic, but if I did, this is what it would look like.
ETA: Owing to a seriously awesome editor at Dial, this page will actually appear in Dragonbreath 2. She's so good to me.
