Jay Lake's Writing Process (This has a link to a contest, and to various ebook formats. I originally thought the title a poor choice until I started reading and realized it was perfect.)
I've been friends with Jay almost since he started writing professionally--humorous, friendly, fun and often interesting to hang with. I fondly recall our drive to Wiscon, the conversations and The Rolling Stones marathon. A good man in many ways.
I'll write a full review later, but it is full of Jay Lake's writing wisdom. Frankly, his ideas on story ideas are mystical mumbo-jumbo (sorry, Jay), but I'm sure they would be useful to those with a very organic writing styles. However, much of the other stuff has valuable writing nuggets: names, productive lifestyles, the business, and world-building details.
For years I've wanted to move out to Oregon, to live near Jay and the Wordos workshop, but couldn't figure out a practical way to do so. This ebook is a good substitute--it makes it feel like you're in conversation with the writer.
I highly recommend it.
