In the city of Fathach, giant hunters are equivalent to local heroes. This is because the city’s very walls are built from giants’ bones, and the townsfolk rely on their elite hunters to keep them not only prosperous, but also safe. For, as everybody knows, giants are wild, violent, senseless creatures…aren’t they?

13-year-old Jacq Dyer is the daughter of two renowned giant hunters–although she’s never had much stomach for what they do. Rejecting the attention that comes with such famous lineage, she prefers to spend her time tinkering with computers and mechanics on her own. Her home life has been even more strained since her mother, Cassie, disappeared on a hunt six months ago–leaving her alone with a father who doesn’t understand his daughter’s recalcitrance.

But an unexpected event at the local processing factory brings the reality of giant hunting much closer to Jacq than she could ever have imagined: close enough to end up face to face with an actual giant. Now, lost and injured in the wilderness outside Fathach’s walls, Jacq and her new giant acquaintance, Corman, will have to work together if Jacq is ever to find her way back home–and if Corman is ever to find his father, recently taken by hunters…

The enmity between humans and giants will need to be put aside if these two youngsters are to make it safely into the city. But could it be that there is a whole unspoiled world to discover right outside its walls–and world-changing lessons to be learned to protect the future of both Fathach and the Underhill Giants?
