Wolves at the Gate (Drew Goddard, Georges Jeanty, Joss Whedon, 2008) is the latest in the Buffy Season 8 series of graphic novels. It's funny, it's fast-paced, it has some great visuals...and one sucker-punch of a character death. Joss sure does that a lot, doesn't he?
You know, I can't promise that I'll never kill a character my readers care about. But I hereby pledge my protagonists' lips are not poisonous, nor are their beds preludes to the long sleep of the grave. In other words, I promise not to kill anyone they kiss or sleep with within 24 hours of their first encounter!
