The Dunbar brothers are living - fighting, loving, grieving - in the perfect chaos of a house without grown-ups.

Today, the father who walked out on them long ago has just walked right back in.

He has an unexpected request: Who will build a bridge with him?

Seizing the chance to come to terms with a traumatic secret, Clay is the boy to accept.

Such superhuman feat, he believes, will be the healing of him.

But why is this boy so broken? And what will it take to put his family back together again?

At once an existential riddle and a search for redemption, this tale of five brothers coming of age in a house with no rules brims with energy, joy and pathos.
