The book is The Magic Candle: Facts And Fundamentals Of Ritual Candle-Burning by Charmain Dey.
Don't let appearances deceive you. This is more of a booklet, a mere 62 pages in length. Though it is very short, there is more useful information in it's pages than similar "candle magic" books that are a 100 pages plus. In this book the reader will learn the types of candles burned in magic and how to properly use them. Included in the book are sections on magical oils, incense, magical color correspondence, seals, and planetary tables. This book is great for individuals interesting in learning candle magic. The only downside of the book is that there are a few errors but I will not nitpick here.
On a scale of 1 to 10, with 1 being the lowest and 10 being the highest, I give the book a 9. I would definitely recommend that practitioners have a copy for their personal occult library.
