11-22-63 by Stephen King

This is the best thing King has written in a while. Duma Keys was good. Cell, not so much. Under the Dome was ok, but his best, the characters shallow, he has done better.

Then this one. One of his best. If you like historical fiction, Stephen King's writing, and are in to the Kennedy assassination at all, you will like this one. One of the best books I've read recently.
