Mostly I write fantasy, but recently I've been toying with the idea of a contemporary, but not just any contemporary, nay! One set in and around the lives of the members of a book club. I thought it'd be cool for readers to see how the characters enjoyed books that the readers themselves had read. Such as TFioS or SA or Mistborn. I think it would definitely be fun to play with the characters discussion of the books, making some really enjoy some, while making other characters despise them.
I dunno, just a tiny idea I've had for a few weeks now. Although it is quickly taking up more of my attention. Alas, I may have to set aside my fantasy shortstory collection for an actual novel soon.
