I have been avoiding this one. My father has some sort of line on new (soon to be) bestsellers and he read it early. I remember how he talked when he was reading it and so, I was avoiding it.
I have never read a book like it. It is quite readable, despite the subject matter, and I didn't want to stop. Two things: Hope is nothing tangible. It is something we conjure up, and it does not matter if at the end there really is something worth hoping for. And, none of us knows what we're capable of. Some things we think we know are not true, other things we can't even imagine yet.
