Aliens are real. Diana Brooke knows this. They come like burglars in the dark, stealing the Earth's natural resources. She makes them pay for their thefts by tracking them across the planet and robbing them. Advance tech brought in good money on the black market. On a remote island, the group she's tracked isn't taking from the planet though. They're abducting humans.
Crypto is an Intergalactic Intelligence agent hell bent on tearing apart a human trafficking ring, but he's separated from his team. Many slavers guard their island base and human casualties will be high if he attempts a rescue by himself. Then he chances upon a female human clad in mismatched alien warrior tech. She is the exact opposite of his anticipation of the human race.
Diana makes it clear she hates aliens, but is willing to put aside her prejudice to help him save her people. Crypto's advanced nanotech makes him appear like a man, but he's really nothing like a human. Can he steal this thief's heart so when he reveals his true identity she can see past their differences?
