Well, Makers is finally out in full. See the
official site for free downloads in various formats. If your preferred format is not there, keep an eye out as people upload conversions on a regular basis. Usually his books show up on Feedbooks after a short delay as well. Right now there is the usual plaintext/html/pdf(s) and ePub and LRF. No idea on the quality level of the ePub and LRF as they are fan submitted.
Anyway, it's supposed to be pretty good.
