LORD OF THE RINGS
Need I say more?
I don't think Tolkien, with his incredible imagination, could have seen the success this book has had. And for those of you who have been living under a rock, somehow missing this book, read it. Read it now. It's an incredible epic built upon a fantasy empire. Orcs, Hobbits, Elves and Trees, all speaking to you and telling tales.
FYI, quick warning, beware of the edition you purchase. Though I have nothing against paperback formats, there are numerous complaints from people out there about some recent versions that have had spelling errors and sub-par glue. Yes, I said glue. The books supposedly fell apart. So do your research.
It's well worth the purchase. Buy quality!
