Random House is offering some sf/fantasy titles for free over here.
I will probably be snagging one myself. I’ve read Red Mars, and have a hard copy of The Assassin’s Apprentice at home that I keep meaning to read. Suggestions from among the remaining three?
If you’re looking for a good read off of that list and have a craving for spectacular sf, you can’t go wrong with Red Mars. Be warned: you’re going to want to go on to read Green Mars and Blue Mars afterwards. Clear your calendars!
