That was the first book I got about crystals after I was doing my search on the internet & came across Energy Muse! It’s a great book! My daughter will use it when she has questions & I’m not around to help her out. I even have a crystal journal booklet for her so she knows which stones she has been given or picked out from my collection. 
I knew you had also taken the Advanced Practitioner Course, but didn’t know if you had anything else to add & I didn’t want to put you on the spot 
@Phoenix_Rose. Both @christina4 & I took the crystal classes through the Love & Light School - Ashley & she also has Mimosa Spirit Shoppe (Love & Light School Store 
) & there are some free downloads but also great crystals & things to purchase as you are able to or would like to based on how you work with your crystals.
