The Holographic Universe by Michael Talbot when I was in my late teens. I had never heard about Buddhism before or anything like the ideas he presented.
Grant Cardone's Be Obsessed or Be Average last week.
Finally, but mostly, Maurice Nicoll's Psychological Commentaries on the Teaching of P.D. Ouspensky and G.I. Gurdjieff, though I recommend reading what is widely considered the "introductory" text, "In Search of the Miraculous" by P.D. Ouspensky.
