For anyone I recommended this to when I was starting out as polyamorous: I'm sorry.

For funsies I went through this book again, and... in retrospect, there is very little "practical" knowledge to take away with, other than the very basic things. So as a jumping-off point this book is ideal, but not for more than that. There's a lot of fluff, and feel-goodness... but if you're looking for answers/advice this book will frustrate you.

When this book is mentioned, More Than Two and Opening Up are usually not far behind in being recommended. I echo that sentiment. Look those up.
