I agree this I have read some of the WACKEST books and seen some of the most HORRENDOUS movies after loving the other version of it. I usually hate reading a book after a move because then I'll know the end, but I do it the other way all of the time.
If you haven't read this book, you need to. It is beautiful and luckily it is the first of a trilogy. Trust me on this. If you like really beautiful, interesting, non-cheesey non-Twilightish romance novels, this is perfect for you.
