A novel of family and secrets, as twelve-year-old Jack learns to grow up without the presence of his mother.

Jack is just twelve years old when he rushes down the hill after his mother's car on his bike, desperate to reach her before she reaches the lake. What happens next cannot be undone. Jack's life changes just at the moment he is entering those dizzying years when he will transition from boy to man; when nothing makes sense at the best of times.

Yet Jack is not alone. Enveloped as he is by his extended family - his ferociously loving Nana; Grandad, given to sudden bursts of rage; his earthy uncles Haulie and Theo who want to show him what it means to be a man, and the irascible JJ who resents him deeply. Then there is beautiful aunt Rose, whose mere presence ignites every atom in his changing body.

But how can a boy with so many questions, in a family with so many secrets, understand the person he is becoming? Without his mother to ground him on the earth, will he spin off into the stars?
