Andrei and the Hellcats — Marie Vibbert

Andrei is a sex-bot who loves his job as hospitality manager at Near Jefferson Station, but when a space biker gang brings a handsome prince to the station, his evil queen mother follows, upending Andrei's life and kidnapping his robot-sister. Now he must find her and rescue her, across the galaxy, with nothing but his sassy fashion sense to aid him, and of course, the Hellcats.
