Where Reasons End, by Yiyun Li

A beautiful and moving book about loss and mourning. Written in a sad tone, but never cheesy, one can feel the sorrow but also the resentment of the narrator facing something she cannot understand and accept - and we never understand either, because the son's act is never explained, and his voice is not really his, but his mother's perception of him, incomplete as it must be. This is one of the great strengths of the book, in my opinion, the way we can never really know what goes on in other people's minds, even the ones closest to us, and how we try to fill in the gaps with whatever we feel we know of them, to try to make sense of their actions that hurt us most, or at least to build a plausible story that can help us to deal with the pain.
