Everyone is right: this book is great. I somehow knew (or certainly hoped) before picking it up that it would be just the kind of book I like to curl up with and read straight through, and that's pretty much what I did. I read it over two days when I was sick with a cold and it was just the right book for that. I think it would have been good under other circumstances too, but it was absolutely perfect for the circumstances I was in.
Having finished All the Light We Cannot See, I have nothing particular to say about it. I was contemplating, yesterday morning, what I might possibly write about it and I thought of my ex-husband who had a complaint about some books that I used to tease him about: he didn't like that he liked them. The only specific time I remember him voicing this complaint was while reading Jonathan Strange & Mr. Norrell. A friend gave me a copy of the book and I devoured it then passed it along to my ex. Like me, he couldn't put it down, but it made him so mad! He felt like he was being emotionally manipulated (I suppose he was) and it drove him crazy. In the end, I think he would have said that he didn't like the book, because he didn't like what it did to him. I, on the other hand, love books that drag me in and don't let me go. All the Light We Cannot See wasn't an extreme example of this, but it was the kind of book I could throw myself into for two straight days without coming up for air.
