Watch the Skies, and free ebooks from Tor

Saw this around (from Lenneth’s post, actually): Tor Books has a promotion called Watch the Skies, which seems quite mysterious but has free digital books as part of it! Obviously this deals with the science fiction and fantasy genre, and the next book (at the time of this writing) is Old Man’s War by John Scalzi, 2006’s winner of the John W. Campbell Award for Best New Writer.

This sounds promising, so I signed up — I love me some SF/F.
