This book contains 72 different angels with their sigils and their invocation and these angels can assist you in any part of your life, so is very good for anyone who want to work with angels, If it takes an angel it describes that angel so you the practitioner will know how that particular angel is and it goes further to give you the sigil and the invocation words and gives you anything necessary to know about. I highly recommend this book for you if you want to work with angels.
