The second book of the Chasing Graves Trilogy. Caltro Basalt is still dead, still bound, and still the best locksmith the city of Araxes ever produced — which is exactly why nobody who owns him intends to let him go. Galley's afterlife economy tightens here: the shades do the labour, the living trade the coin they are worth, and the widening war over the throne turns every debt into a weapon.
