Here 'tis. Enjoy.
"The Atonement Tango" will be available -- for free -- on Tor.com on January 18 of the new year.
You don't need to wait quite that long for your Wild Cards fix, however. On December 21, Tor.com will upload another WC story, Carrie Vaughn's "The Thing About Growing Up in Jokertown."
And don't forget to check out the older WC offerings on Tor.com, some amazing original fiction by David D. Levine, Daniel Abraham, Cherie Priest, Carrie Vaughn, Paul Cornell, and Walter Jon Williams. You can find them all with a simple search, and read them all for free. The Recycler, Jonathan Hive, the Button Man, Earth Witch, the Understudy and Elephant Girl and the Sleeper, Pop Tart and Golden Boy... they are all waiting for you on Tor.com.
