Spy by Cyndi Friberg

After ten years as a field agent, Kaden Lux is ordered to babysit a bunch of scientists. Yes, the scientists are working to free the magic locked inside each battle born soldier, but his skills are utterly wasted on a spaceship. Then he encounters a feisty reporter named Lexie Ward.

Lexie deals with her sister’s disappearance as she deals with any mystery; she starts digging. Her tenacity has served her well in the past, so she sees no reason to change her approach. But the clues soon lead to a military outpost hidden on the dark side of the moon.

Not sure if she’s lost her mind or if Earth is in serious danger, she’s forced to trust an arrogant, yet devastatingly attractive alien named Kaden Lux. Sparks fly and passions flare as the reluctant partners delve deeper into the mystery. And Earth’s fate hangs in the balance.
