Quick recap
Susan tells Harry they have a daughter, Maggie, kidnapped by Duchess Arianna of the Red Court. The Court plans to use the girl in a blood curse that would kill all her relatives, Harry included. Harry's office blows up, the FBI investigates him and his building is firebombed, leaving him with a broken spine. To get power and healing, Harry agrees to be Mab's Winter Knight. On the Yucatán Peninsula he kills Arianna in a duel, but the Red King breaks the deal. Harry uses Susan herself to turn the curse back on the Court, which is almost wiped out. He leaves Maggie with Father Forthill and, on Thomas's boat, is shot and falls into the lake.
