Simak

The Moon of Hesperia: Phoenix, a gifted but amnesiac policeman, witnesses the murder of his teammate. His investigation leads him to Solar Corona, the city-planet of all debauchery, where he crosses paths with the simaks, transhumans designed for prostitution who were supposed to have been eradicated as a result of repeated bugs. In the heart of this violent and corrupt universe, his thirst for justice will lead Phoenix on a trail to discover the simaks' origins.
