David Brin's Heaven's Reach. I am apparently missing the middle novel of this trilogy, Infinity's Shore.
Scott McCloud's Making Comics. Maybe I should have gotten Understanding Comics first, but w/e.
David Weber's Off Armageddon Reef. Saw this on sale at B&N, but decided to wait until I could find a copy in the library first - and then forgot the title. :(
The Five Fists of Science, which looks goofy but fun.
Oldboy. Should have realized this was a manwha before it became a movie.
C. J. Cherryh's Forge of Heaven, which looks like a sequel to Hammerfall.
