He thought he knew who he was. Then he read his mother's letter.

For fifty-two years, Harry has known exactly who he is and where he belongs. Then his mam dies, and the letter she leaves behind takes it all away.

The man who raised him, the dad he has loved his whole life, is not his biological father.

Grieving the mother he has lost and reeling from a secret she kept his entire life, Harry sets out to find the stranger whose blood he shares. He has a name. He has a city. He has no idea what he's walking into.

But the search gives him more than answers. Along the way Harry finds unexpected friendships, a little grace, and the beginnings of a question he never thought to ask: what really makes a family?

A warm, funny and deeply moving novel about grief, forgiveness, and discovering that family isn't only about blood.
