My new short story "String Theory" is free for another 24 hours. After that, you will have to sell some of your gold bullion and pony up $0.99. By waiting until the last minute, you get the advantage of obtaining an updated version of the story without a typo on page one (yes, a leopard does not really change his spots in a different medium).
You can get it on Kindle here.
And my novel BMOC is still available on Kindle and as an actual dead-tree book.
