Stephen Daisley's astonishing debut novel is a story of war and of love--how each changes everything, forever. Traitor is that rarest of things: a work of fiction that will transport the listener, heart and soul, into another realm.

What would make a soldier betray his country?

In the battle-smoke and chaos of Gallipoli, a young New Zealand soldier helps a Turkish doctor fighting to save a boy's life. Then a shell bursts nearby; the blast that should have killed them both consigns them instead to the same military hospital.

Mahmoud is a Sufi. A whirling dervish, he says, of the Mevlevi order. He tells David stories. Of arriving in London with a pocketful of dried apricots. Of Majnun, the man mad for love, and of the saint who flew to paradise on a lion skin. You are God, we are all gods, Mahmoud tells David; and a bond grows between them.

A bond so strong that David will betray his country for his friend.
