James Clavell's "Shogun" I have worn out three copies of it I reread it so often. Have it in Kindle now

I have to admit that the romantic in me loves Pride & Prejudice.... It's cheesy but I can't help loving it. I read it through about once or twice a year.

On the other hand, the cynic in me love Orson Scott Card's Ender's Series (polar opposites).

My favorite book has stood the test of time. It's Jane Eyre by Charlotte Bronte. I've read it several times and I love it more everytime I read it.

Something tried and true for me. One of the most ancient books out there on philosophy of sex and sex in general; the Kama Sutra.
