Joe is 17, a gifted artist and a brilliant older brother to 12-year-old Finn. They live with their Ma and Da in a Dublin tower block called Bojaxhiu or 'the Jax'. It's not an easy place to be a kid, especially when your father, Frank, is the muscle for the notorious gang leader Dessie 'The Badger' Murphy. But whether it's daytrips to the beach or drawing secret sketches, Joe works hard to show Finn life beyond the battered concrete yard below their flat. Joe is determined not to become like his Da. But when Finn falls ill, Joe finds his convictions harder to cling to. With his father now in prison, his mother submerged in her grief, and his relationships with friends and classmates crumbling, Joe has to figure out how to survive without becoming what the world around him expects him to be.
