Knitting Rules!, by Stephanie Pearl-McPhee
Another wonderful book by the Yarn Harlot. If you're a knitter who is at all active on-line I'm sure you already know about this book.
Personally, I love Stephanie's writing style. I love visiting her blog and gobbling it all up! This particular book has a lot more practical knitting info than her first two (including the sock recipe!)
That's really just about it for that one. I really like her books in general and can't wait for the next one to come out!
