I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
I love that so many people want to travel back to the Pliocene in some kind of costume. I think that's very realistic!
Also enjoying the equality between men's POV and women's POV in the writing. It passes the Bechdel test with flying colours.
