Bullies, Bastards And Bitches: How To Write The Bad Guys Of Fiction - Jessica Page Morrell

There's a whole chapter here on dark heroes and bad boys and I think it's particularly well written on the differences between the two. Also, judging from the definition given to a "bad boy" in here - I've learned that while many "bad boys" in New Adult and YA have some of these same traits, what makes many of them fail or turn off the reader is the fact that they're not written very well or compelling for the stories that they're shaped within.
