1776, by David McCullough
McCullough is one of the most literate and accessible historians. A favorite writer of mine, crossing all genres.
Amnesia Moon, by Jonathan Lethem
Post-apocalyptic fiction, read in one sitting. Much less depressing than The Road, but what isn't?
I wish I were reading Harriet the Spy right now and discovering "The Walrus and the Carpenter" for the first time.
