A bloodthirsty evil threatens humanity—and one man's war against the slave trade—in the final novel in the classic sci-fi Emancipator trilogy.

Slavery is the corporate foundation of the powerful Pangalic Worlds where Ruiz Aw leads a dangerous double life, as an enforcer for the Art League that so brutally controls its slaves and as an Emancipator dedicated to eradicating the cruel business. While Ruiz is still striving to free slaves across the embattled cities of the dangerous world of Sook, the pirate Lords are ruthlessly plotting. A death cult is luring in humans with an unending desire to see them suffer. Even the powers of the Art League have no jurisdiction over this killing machine. The growing domination of the Orpheus Machine will force Ruiz and his fugitives to fight for their lives against a supreme evil unlike anything they've ever witnessed before.
