Jennifer is in charge of managing all the wizards under her care and providing them with work, as well as filling out all the governmental jobs that are associated with performing magic in the current era.

The wizards of Zambini Towers begin noting that their powers seem stronger than before, and magic appears to be building instead of slowly depleting like it has for the past four hundred years.

She gets a crash course in dragon slaying, takes the oath and immediately becomes the new Dragonslayer when her predecessor suddenly crumbles to dust as his true age finally catches up with him.

His greed and that of all the millions of people waiting outside the dragonland in the hopes of securing a piece of land for themselves when the magic shield dies with the dragon enrages Jennifer.

Eventually, she does slay the dragon, and is filled with such white-hot fury that she lets out a scream so loud and so powerful it unleashes what the wizards speculated was building: Big Magic.

Unlike other Jasper Fforde novels, there are no obvious references to specific works of fiction, even though many standard elements of fantasy are used for comic effect.

The novel was adapted into a TV movie by Blueprint Pictures and Motion Content Group, and broadcast on Sky One on Christmas Day, 2016.
