Crossfire (Star Kingdom #4)

For the first time in his life, roboticist Casmir Dabrowski is headed to another star system as an advisor for the Kingdom space fleet. He’s being given a chance to prove himself to King Jager by helping find the ancient artifact he inadvertently lost. It’s best not to think about what might happen if he fails...

But with technologically advanced astroshamans after the artifact, not to mention the deadly mercenary captain Tenebris Rache, it’s not long before the mission collides with disaster.

Soon, Casmir and his friends are caught between warring factions, and he must choose between what the king would want and what he knows is right.
