Fantasy written for younger listeners has to move. A teenager will forgive a great deal but not a slow first hour, and The Inquisition is shaped with that audience in mind. Our catalogue files it for children and families as well as for teens and young adults, which puts it in the comfortable middle ground a whole household can share.
Taran Matharu writes it as part of The Summoner Trilogy, and the sequence title sets its own terms: summoning is the engine of this world. An inquisition, meanwhile, promises judgement, pressure and an establishment that must be answered to, which is generally where a fantasy series starts to get interesting.
