I vouch against reading anything LaVey: it's not real Satanism.
You said "life-changing", not necessarily occult books then. I suggest these books that teach how to manage money, something that is not done in school and something most parents have many misconceptions and erroneous notions about:
~ Rich Dad, Poor Dad~ "The Intelligent Investor" - by Robert Graham
Occult-related, I can advise everything by Mantak Chia. You can also try books are listed as sources under our HPs articles and sermons. For example:
~ The Return Of The Serpents Of Wisdom - by Pinkham Young~ Proof Of Vedic Cultures Global Existence - by Knapp Steve~ The Alchemical Body - by Gordon White~ The Secret Teachings of All Ages - by Hall's Manly• Irish Origins of Civilization - by Michael Tsarion • World Gnosis: The Coming Gnostic Civilization - by Mark Amaru Pinkham • The Black Sun - by Peter Moon • Realm of the Ring Lords - by Laurence Gardner~ "The Lost Civilization of Lemuria" - by Frank Joseph
~ The Holy Science - by Swami Sri Yukteswar
~ Genesis of the Grail Kings - by Laurence Gardner~ Introduction Into Magic - by Julius Evola~ The Hindu Temple - by Alain Danielou~ Kundalini Yoga as taught by Yogi Bhajan, The Chakra's~ Tantra Yoga, Nada Yoga, Kriya Yoga, Swami Sivananda~ The Hermetic Doctrine - by Julius Evola~ Guardians Of The Holy Grail - by Mark Pinkham~ The Blue Apples - by William Heny~ Siva And Serpent Worship - by Hyde Clark
