Aloha Josiah,
"The Energy of Scent" article in the Vol 1, Issue 3 Space Newsletter would be a good place to start if you have it.
I don't have a single great book to suggest. I know a lot of very talented "blenders," Young Living Oils, for example.
If you'd like to get into some someone who is impecable about the quality of their work with phytoesences, then check out Dr. Berkowsky at:
www.NaturalHealthScience.com. I think you can still download some back issues of his journals. His work will take you a bit deeper than most others. Bodyworkers how haven't stumbled onto his blends are missing out.
Otherwise you can head to a bookstore and do some muscle testing regarding the books.
Much Love, Shawn
