Afterworlds is out NOW, but my tour is totally over. Sorry if you missed me. My next tour will be in October 2015, when my next novel comes out.

I sometimes do random appearances between tours, and they will be listed here. But the best way to stay apprised is to follow me on Twitter at @scottwesterfeld.
