I am with all of the readers before me who have described this book with love, thoughtfulness and even heartache, along with the many other feelings that can be hard to evoke. Now I understand. Finally. 
 Quite some time passed (2-1/2 years since publication & 6+ months on the physical bookshelf in my home) before I finally pulled it down from my shelf. I remember asking the GR community a question about The Nightingale, the other blockbuster WWII book so often compared with this one. I had asked if the hype was true, and many answered that it was, but a few suggested I try All the Light We Cannot See. So I put them both in my TBR, and read The Nightingale soon after. Loved that one. Then I let a year go by. I read a half dozen or so books about the War during that year. My eyes would wander over my shelf of books, stop for a second on Doerr's book, before moving on - "No, not right now". Why not? Little reasons that don't add up to a hill of beans. Anyway, a GR friend's 2016 review changed my mind. I opened its pages to begin reading this gorgeous story about Marie-Laure and Werner, just two young strangers caught on opposing sides of a war that will change history and so many lives that lie in its path. It was beautiful, and tough, and stirring. I could hardly put it down (which is my review in a nutshell). The desire to read a book at every possible opportunity speaks volumes. What more needs to be said?
