The books I'm reading right now are "The Prince" by Niccolò Machiavelli and "Mars Crossing" by Geoffrey A. Landis. The first one is a book I bought some time ago, but never really finished, and the second one is from a library.
After I finish both books I plan to read "The Art of War" by Sun Tzu. I've only read some quotes, but it seems to be very interesting.
I've recently finished reading two books for a read-a-thon. The review of one ("The Stealers of Dreams" by Steve Lyons) is already posted and I hope to finish writing the review of the other one ("Winner Takes All" by Jacqueline Rayner) this week.
Sadly I don't have much time to read and mostly read on the bus, but I try to read at least two books every month.
