This is a sci-fi-esque story about the opportunity to know the length of one's life and how the power of that knowledge influences relationships and decisions. The story follows a cast of characters with interconnected lives, looking at both the macro and micro level response to knowing the lifespan of yourself and others. For some reason, I found this book hard to get through; it just did not grab my attention. I liked the overarching ethical question of "what would you do?", and I feel like the ending made this book worth reading, which is often not the case. Most of the story was only "ok", but the author did an excellent job of tying the story together and closing the book in a way that made it more memorable to me.
