Young Rosa Somberly suddenly inherits the title "Judge of the Court of Last Resort" following a courtroom catastrophe.

Benji, an urban explorer and thief, breaks into the Judge's house and is sentenced by the old Judge's corpse to protect Rosa from the follies of the human world and the cruelties of the elementals.

Together Rosa and Benji learn to navigate the laws of both humans and elementals in the Court of Last Resort where anyone (or anything) can seek justice.

But Rosa and Benji face their greatest challenge as the eternal clash between Tau al-Gorz, the Sweeper of Progress, and the Caiman, Protector of the Rivers and Forests, reaches a chaotic world-wide climax.

To judge the very same case that killed her father, Rosa, Benji and his urban gang must travel 4000 years through time to the Minoan civilisation, where the ancient conflict between progress and the natural world began.
