Forgive me while I crow for just a moment: Mr. Penumbra just hit what I think is a new peak in the Kindle store. It’s the 937th bestselling item in the entire Kindle universe. The fourth-bestselling short story. The third-bestselling “techno thriller.”
The sad truth: As best I can figure, that rank was driven by about 30 copies over the past two days.
Alas, Kindle. Your universe is small indeed.
