Forever Lover. SDS Robots, #5

Joon, the SDS robot and former premier sex worker at the Humanistic Garden brothel, is now in a relationship with Benjamin Smith, the AI robotics genius inventor and trillionaire investor from Earth (SDS Robots #2). Benjamin loves being submissive to Joon who knows exactly what he needs for his sexual satisfaction. Benjamin has been charged with crimes against humanity for creating the SDS hybrid robots, so Joon travels to the Sagitta Settlement where the trial will be held.
Along the way, his transport ship picks up Ash and Lin (SDS Robots #1). Lin is a former SDS hybrid robot who later had an operation to turn fully human. Once on Sagitta, Joon represents Benjamin at his trial and some surprise witnesses show up to testify as Benjamin's fate hangs in the balance. Can Joon prove Benjamin's innocence in a universe where SDS robots are feared and misunderstood?
