About the book
Chicago wizard and private investigator Harry Dresden learns he has a daughter when his former lover, Susan Rodriguez, calls to tell him she has been kidnapped. Susan has spent years resisting the vampiric infection that separated them; now Duchess Arianna of the Red Court holds their child, Maggie. To rescue her, Harry seeks help from people and supernatural powers whose demands he has good reason to distrust.
Reader notes
Fast, violent action is interrupted by Harry's gallows humor, even as the rescue grows increasingly grim. The twelfth Dresden Files novel draws much of its emotional weight from relationships established in earlier books, so familiarity with the series matters here.

The rescue grows increasingly grim, with strong violence and fast action as Harry tries to save his kidnapped daughter. His gallows humor interrupts the tension, but the tone remains dark and suspenseful.

About the author
Jim Butcher
Jim Butcher is an American fantasy writer whose series range from present-day occult detective fiction to secondary-world adventure. His plots are built for momentum. An immediate case or mission opens onto layered factions, formal rules, and conflicts larger than the protagonist first understands. The prose is direct and conversational, with quick dialogue and dry wit carrying readers through elaborate supernatural systems. He repeatedly works with capable outsiders whose disadvantages force them toward improvisation, investigation, and uneasy alliances. The Dresden Files gives this method its clearest shape. In Storm Front, Chicago wizard Harry Dresden follows linked murders through organized crime, illicit magic, and the scrutiny of a governing wizard council. Later books widen that detective framework without abandoning it. Summer Knight turns a murder inquiry into diplomacy and coercion between rival Faerie courts, while White Night moves from an apparent suicide to a conspiracy involving vulnerable practitioners and competing vampire factions. Furies of Calderon shifts to epic fantasy, using intersecting viewpoints and political intrigue around Tavi, a boy without the elemental powers his society treats as essential.
