I wrote a short story, set to be published on May 20, 2013.  It's VERY SHORT but it will be free.

Mara longs to escape the harsh city she grew up in. Plagued by disease and death, New York City was the last to fall to the war against Human Nature. Mara and her sick, crippled mother seek refuge in solitude, out of the city. But there are crazed groups of violent gangs and religious cults just as harsh, perhaps even worse than the gangs.

This is not, however, the project I was referring to on Twitter.

I plan on writing 2 novellas and one-three short story(ies) a year and I am super-excited to announce my new project after Corpse Garden is released.  :)  Thank you!
