Book review - 21 things to Know Before Starting an Ashtanga Yoga Practice

I just bought and read this book, and I loved it.  It really is a book to read before you start practising, or rather, near the start of your practice.  It is full of helpful advice, some new, some old.  It's not really a book, more a collection of her blog-posts bundled together for a kindle, but the format works well.  At $1.99, it's worth the purchase.
