I read it. I liked it. It's well written, has some funny asides and foot notes. It talks about some of the common first year cases in a way that made me #1 remember cases I'd forgotten about and #2 made me remember why I'd tried so hard to forget them in the first place. Also, you can learn some magic from it.
It's written in a manner consistent with his blogging. So, if you don't like that, you may not like the book. But I really enjoyed it.
