Moon Madness - Dazon Agenda, #4

When General Orix Monash defected from the Dazon armada to protect Earth, he expected some fear and suspicion. What he didn't expect was to find his mate among the Earth women at the Moon's consulate. Mary Catherine Jones is the caretaker for the orphaned human-Dazon hybrid babies, but when he looks at Mac, he wants to take care of her forever. She feels the pull too, and they're quickly drawn together-and drawn into a plot that involves a traitor and the first battle in Emperor Aryk's bid to steal Earth women for mating purposes.
Each book in the Dazon Agenda series focuses on a different couple while expanding the overarching plot. It is recommended to read the books in order.
