A lot of people like Robert Jordan's Wheel of Time series. If she's into fantasy, there are, like, six or seven books out. Harry Turtledove also has a shitload of alternate history books out. One deals with the confederacy winning the Civil War. Another is a series about aliens invading during the middle of WWII. It all depends on her taste for sci-fi.
whomod said: I generally don't like it when people decide to play by the rules against people who don't play by the rules. It tends to put you immediately at a disadvantage and IMO is a sign of true weakness. This is true both in politics and on the internet."
