Book excerpt: Harry Turtledove, author of perhaps the most famous alternate-history novel about Robert E. Lee (The Guns of the South, 1992), here returns with Lee at the Alamo, a look at what the great military leader might have done under only slightly different circumstances. In the history we know, General Robert E. Lee felt compelled to fight on the Confederate side, because honor (as he saw it) forbade him to take up arms against Virginia, his native state. But what if the demands of honor had led him in the other direction altogether? At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.
