Ask HN: (Audio)book recommendations / community

I've got a new credit to spend on Audible, and I was thinking of asking people for recommendations. I realized, all the people I wanted to ask were HNers. Then, I thought, HN would actually be the exact community I would want to turn to for book recommendations.

I'm curious if an HN book community exists anywhere? If not, would people be interested in one? Know of any other communities with a similar center of gravity of systems design and small business?

Also, please actually suggest a good audiobook if you've got one in mind that's outside the mainstream that a HN minded person would enjoy.
