A former manager of mine had a whole side gig writing direct-to-kindle romance and erotica for quite a while. Not bad money in it either.

Those two seem like the best time:money ratio genres. Lots of turn over, lots of fans with pretty forgiving quality filters.

I'd be happy selling my one book fairly well. Though I keep hearing that it's series and series of series that do the best.
