This is a great book. It's one of those books that you pick up and read it in one or two sittings, not even realizing you're reading. You put it down and think, "Huh, that was a good book," and then go do other things. And a day later you realize, "I'm still thinking about that book." Another day goes by, you realize, "Wait, I'm STILL thinking about that book." This goes on and on, and you understand that you've read a book that has made a lasting impact on you.
The story - no spoiler here, don't worry - is about a man who goes mute and spends the rest of his life painting one long, incredible picture, that goes on and one for miles. When he dies, his sons come back to sell the picture and realize one year of their father's life is missing from this long painting. As they search for that missing year - get the title now? - they discover who their father really was. It's a beautiful story and I really recommend it. And a week or two weeks or a month after you've read the book (well, for me it's only been two weeks since I read it, so maybe I'm projecting a bit), you'll still be thinking of your life in terms of how you'd paint it.
