Heh, I was hoping you were talking about this book when I read the thread title. I actually finished it about a month ago; it was a great read. As much as I love the little "twist" (for lack of a better term) of the beginning I think the ending is the real gem. The best way I can describe it is warmly terrifying.
Agreed. The ending is unique and stands in stark contrast to the end of The Last of Us. It even seemed preferable.
