There is now an Audible version of Pulchritude available through Audible. It's supposedly also available through iTunes, but I can't find it there. If you're not an Audible fan, you can get snag a complimentary Creative Commons MP3 version here.
(Also, the Pulchritude page on Acacia Moon Publishing now looks nicer. Thought I'd mention that.)
This audio book version cost $500 to create and I start with 25% of the Audible price (which varies based on whether people are members or not, I believe), to be increased up to a theoretical 75% as sales go up over time. But basically I have to sell 100+ copies to earn back the investment on this baby. Since I've sold all of 30 eBook copies of Pulchritude, we'll see. Possibly my next book won't have an audio book version, but I wanted to try this experiment.
