New problems grow from old doubts, twisted promises and a friend as dangerous as any foe.
Harry Dresden is feeling happy. No one's tried to kill him in nearly a year, and the worst problems he's had lately is trying to remove the stains his apprentice bungled into his carpeting. The future looks fairly promising. Unfortunatley, the past isn't always so bright.
An old bargin placed Harry in debt to Mab, faerie monarch of the Winter Court and the Queen of Air and Darkness. Harry still owes the Winter Queen two favours, and it's time to pay one of them off. It's a small favour that he really can't refuse, but it will trap Harry between a nightmarish foe and an equally deadly ally, stretching his skills and loyalties to their very limits.
It figures. Everything was going too well to last.
