Query: I was haunted by this book

I really can't think of a book lately that I enjoyed as much as this one. I felt immersed in another world while reading it and dreaded when it would end. I miss the characters. I really feel unable to put into words why and how I found this book so affecting, other than observing that the romance and the horrors of war were depicted equally well. I highly recommend it.
