The hedgehog world is collapsing under its own pollution and the crew of the Duweena's Courage, years older and believing their old enemies have been destroyed, find themselves sent to a nearby world, Yurle Minor, to find out what happened to the explorers who preceded them When they arrive, they are attacked by a vicious hedgehog cult, their leader the infamous Walpole, the demon hedgehog of Yurle, and the creations of his pet mad scientist: robots, zombies, and giant machines whose sole purpose is to make the tyrannical hedgehog master of the Universe. But the natives are resisting, and even Walpole learns that being immortal does not protect one from others who would be gods as well. Jonathan Quintain and his faithful companions are tested to their limits: not all will return alive. This is the concluding story in the wonderful and strange Quillogy series.
