My son's 13 and a half, and we've started to share...though he loves Tolkein, and I...blasphemy! Do not. I think Tolkein is a boy's only writer, at heart.
I know that there are a lot of comic book readers who would enjoy romance hybrids...romantic suspense and paranormal romance in particular. I think part of the problem is the old stigma against men trying something that has too much of a "feminine" association.
