+1 for House of Leaves! Didn't expect to see that here. Bizarre and mind-bending. Awesome experimental fiction. Really have to go back and read it again sometime soon.
(And no, there's no eBook - that I know of. You'll err... understand why when you see the physical copy.)
I loved this book, and honestly it's one of the best books I read in the past decade. There does exist an eBook, because I read it on Kindle and I remember I used to wonder how amazing it would be to read it in hard copy. Well, it's been almost 3 years now - time for a re-read in Hardcover!
1. Zen and the Art of Motorcycle Maintenance; I have no words for this except that it was profound and I was ready for it.
2. The Five Dysfunctions of a Team; a classic where history knows better than we do.
3. Special Topics in Calamity Physics; a fictional tale that shows you how damn easy it is to get lost in conspiracy and speculation.
4. House of Leaves; you can't beat a mind-bending horror like that. I live for this stuff.
5. Siddhartha by Herman Hesse; It's 50 pages long, just read it.
6. Tantra Illuminated; A well researched and academic study into the history and the beliefs of Tantra
7. The King in Yellow and its derivatives; The Hanged King lore in the SCP universe is obsessively fascinating to me.
