The series
At a glance.
Boss of the Underworld is an early graphic novel series by Tor Freeman, published by Hodder Children's Books. It follows Shirley into an underworld of odd creatures, alarming problems and comic menace. The joke is partly in the contrast: Shirley is small, but she has the nerve and determination of someone who fully expects monsters to listen. The format is friendly to newly independent readers, with visual storytelling, manageable text and a lively sense of absurd danger. It is less emotionally intense than older fantasy comics, but gives children a taste of quests, monsters and heroic problem-solving.

Shirley takes charge
Two funny early graphic novel adventures about Shirley facing underworld monsters with confidence and comic nerve.
The current Boss of the Underworld books work as a compact standalone collection rather than a developed saga. Shirley vs the Green Menace introduces Shirley's underworld adventure mode, while Shirley vs the Huge Beast continues the same mix of monsters, comedy and unlikely leadership. The books are useful because they offer fantasy peril in a low-sensitivity form: the titles sound dramatic, the creatures look exciting, but the storytelling stays silly and approachable. For readers who like the fantasy shape of quests and monsters but are not ready for Amulet-style intensity, this is a much gentler step.
