Grendel Unit

They are the elite covert unit of the government. Their mission: Hunt and eliminate terrorists across the galaxy, by any means necessary. A four man team, including one very large, very shaggy, alien called Monster, they are Grendel Unit.
But everything is not what it seems, and the system they serve, and kill in the name of, turns on them.
Now, the operatives of Grendel Unit will fight back to regain their freedom, and honor. The galaxy is outnumbered, they just don't know it yet.

An epic sci-fi military saga from Bernard Schaffer, filled with jaw-dropping action, brilliantly realized settings, and gut-busting humor.
