You can buy my book here:
It's $1.99, available only for Kindle at this time, sorry. It's pretty much composition, pulled together with a few ideas regular readers have already seen.
The introduction is pretty complete and accurate, I think, and it's available in the "free preview" amazon gives you. So, I feel like you can make a pretty fair guess at whether the book will suit you before you buy it.
There's my book San Fran Cisco as well. I don't make any money on it, and it's basically a blog post I made a while ago, but you can buy it if you want!
