I really like this book. It is set up as course that should be worked through during a year. Keeping Her Keys is a beginners book, that can be helpfull for advanced practitioners, too. If you're looking for a book that helps you develop a relationship to Hekate and gives you practical advice for ritual and daily practice, this book will help you. That beeing said, i have to add, that this shouldn't be your only and maybe not your first book about Hekate. I would recommend to read at least 1 or 2 other books about her. For example the once by Sorita D'Este and Courtney Webber. You can take this book as a guide and starting point, but you should have in mind that these techniques and rituals are not the only one and true way to worship Hekate.
