I opened this thread again to add a book, and it turns out Jean started off the thread with it. I'm only partway through Mary Kole's book, but I'm really enjoying this one! The beginning is your basic what-is-MG-and-YA, but once you get past that, yeah, it's really for people who are not beginners anymore and need a bit more meat. I'm reading it quickly straight through, and then will be using it as a workbook. In particular, she has great things to say about showing, telling, interiority, and raising the stakes. I definitely recommend it!
