With what should have been the greatest heist of their career gone spectacularly sour, Locke and his trusted partner, Jean, have barely escaped. Now Locke is slowly succumbing to a deadly poison that no alchemist or physiker can cure. Magi political elections are imminent, and the factions are in need of a pawn. If Locke agrees to play the role, sorcery will be used to purge the venom from his body-- though the process will be so excruciating he may well wish for death. Sabetha, a woman from Locke's past reappears, and Locke must choose whether to fight Sabetha or woo her-- and it is a decision on which both their lives may depend.
