You know that moment where you watch a kid start spiraling out of control and you know its going to be ok, but they don't because that moment is the worst moment of their much-shorter lives? That's Nothing. 13 year olds are pretty much as smart as adults, but they lack the life experience to help temper emotions or manage stressful moments.
Nothing has an odd set up - a kid climbs up a tree in a fit of nihilism and refuses to come down for months. Where are his parents? Any adults? They seem content to ignore him and let the kid figure it out on his own. Everything past that, however, feels distressingly plausible. The other kids in his class decide something must be done, and wow do they commit to process of figuring out what. It reminded me of the book The Power by Naomi Alderman. You feel in your soul very early on that its not going to end well, but you just can't put the book down because you have to know.
Nothing is a short book, but don't read it at night, and make sure you read it before giving it to a teen. It would be a very good discussion book, but I think it has to be a discussion book if reading it under a certain age. I know I didn't sleep well the night I read it.
Definitely read it though. 10/10.
