Fifteen-year-old Nix Humbolt doesn't talk much.
He's barely outgrown his Fatty Humbolt days, and although he is taller and leaner now, he has learned it is best to keep a low profile.
He dreams about his only friend's girl, but of course she is hopelessly out of his league.
Lonely and introverted, he is happiest in his father's woodworking shop, where he builds exquisite boxes and tables.
The only battles Nix fights are on his Xbox - until the day he finds the guts to fight for Swiff Dunphy's neglected dog.
Then there is Roxy, Nix's spirited older sister who always knows just how to get what she wants.
But the guy she wants is seriously toxic, and even Nix can see that she is headed for disaster.
All Nix can do is cover for her when she breaks curfew or comes home drunk.
But this time Roxy is about to spiral out of control and change all their lives forever.
And there is nothing he can do to stop it.
