Mia’s new partner? An arrogant, cocky, seven-feet-tall alien warrior.

When a young girl with a striking resemblance to her lost sister disappears on an alien space station, Mia is called upon to bring her back home. She’ll do anything to save this girl’s life. Even if it means working alongside the most arrogant, cockiest Zoran she has ever met.
