Query: The Reader's Digest Guide to Polyamory

Nothing in this book is wrong or out of place, but it's instantly obvious that it's written by a poet and not a prose artist. I personally feel this book has a far greater economy of words than the topic deserves. It's an addition to the books on polyamory which is a rapid, easy read-but left me wanting more. More explanation, more details, more mechanics.
