I mentioned before that I had purchased The Slippery Art of Book Reviewing by Mayra Calvani and Anne K. Edwards, but now I've actually read it. It's a great book if you want to be a book reviewer, and even if you don't. Don't read it straight through though. This isn't a simple how-to book. This is a text of everything you ever wanted to know about book reviewing. It is meant to be read and reread sections at a time and to have on hand to turn to when trying to write a review. I bought it in ebook form and it was well worth the money.
