Fuzzy Ergo Sum begins shortly after the conclusion of the trilogy, involving characters from those books in further adventures and conflicts.

Still in the early stages of colonization, Zarathustra was thought to be devoid of intelligent life until prospector Jack Holloway discovered a race of small furry humanoids, the Fuzzies.

Subsequently, the Pendarvis Decision had declared the Fuzzies to be sapient and thus the owners of the planet's mineral rights, which cost the CZC its mining charter.

What she discovers could put one of several men at risk, among them Jack Holloway and the Chief Colonial Prosecutor, Gus Brannhard.

To make matters worse, the most infamous criminal on the planet escapes from Prison House with the aid of unknown confederates, who have plans that could shake the foundations of the colonial government and the CZC.
