Query: The best book I've ever read (and I've read a lot!)

To give you an idea of how good this book is, I woke up at five-thirty just to read it...for the fourth time!!! This book is great if you love fantasy, romance, and heroines. This book makes you feel giddy inside, and you find yourself holding your breath throughout. This is one of those rare books that makes you feel warm inside, like "It's a wonderful Life" and "the Wizard of Oz" Have fun!
