Milor (A Galaxy Unknown, Book 5)

Terrorists are creating a climate of fear on the planet Arrosa, and although no demands have been made, nor claims of credit taken for the attacks, the Prime Minister believes that the government of their neighboring planet, Selax, is solely responsible. As commander of the only Space Command base in that part of space, Captain Jenetta Carver is responsible for maintaining the peace, and the task of preventing a system-wide war falls squarely upon her shoulders. Meanwhile, several Milora have been observed in the company of an arms merchant's Tsgardi henchmen. The Milori, an ugly warlike race often compared more to cockroaches then humanoid life forms, come from a home planet well outside Galactic Alliance borders. There's an old saying in Space Command that, like cockroaches, if you see one Milora, there're probably a thousand more concealed nearby.
