In the city of Solken, the mark on your skin is your fate. Blue for labor. Purple for power. The color appears at seven, assigned by an Oracle that has never been wrong - and never been questioned.He has no name anyone keeps, and a secret the Order would kill a city to bury: with his hands, he can change a mark. Caste, class, the whole machinery of who is allowed to live well and who is allowed to live at all - he can rewrite it on a child's arm in the hour before dawn.He works alone, until a job goes wrong and he is no longer alone: a former enforcer who walked away from the Order's worst secret, and a man with no mark at all, who does not yet know what that means.But something is changing in the city. The wipe that took his memory is thinning. A vote is moving through the Inner Keep that will erase a quarter-million people the system has decided it no longer needs. And in a hidden room at the heart of the Order, a girl with the wrong color under her skin is asking the one question no one is supposed to ask.Assignment, or fate? They mean the same thing - if the one doing the assigning is a god.THE MARK is the first book in The Circle of Ash: a literary science-fantasy of caste, memory, and the quiet courage of people the system never counted.
