Your commute to work needs more post-apocalyptic heroic songs and interstellar voyaging. Tor.com has you covered, with a nifty free e-book collecting "Some of the Best from Tor.com." It includes stories by Michael Swanwick, Yoon-Ha Lee, Harry Turtledove, Paul Park, Nnedi Okorafor, and myself. You can pre-order the book now, and it'll be available for the Kindle (and other e-readers) on Feb. 14. [Tor.com]
