I've now spent hours trying to write an instructive post on peer review for writers, and I'm sick of it. So in a nutshell: If you're having trouble getting a good critique of your work and you're in a hurry and you don't mind spending a bit of money, go check out Scribendi. They work quickly, their rates are good (compared to other editing services), and you'll get good feedback. I used them to help with my synopsis and was very satisfied.
In other news... Every writer I follow seems to be blogging about the Macmillan / Amazon debacle - I found Charles Stross's post on the subject to be good reading. My own feeling is that Amazon is shooting itself in the foot with this, and that ultimately Macmillan will get its way... but Amazon is a pretty hefty gorilla, so no promises. I just hope I'll be able to order Trade of Queens when it comes out without feeling like a tool.
