Titus Briggs is an Earth Defense soldier, a grunt, a decorated war hero—it's all he's ever known. So when a career-ending injury leaves him lying in a hospital bed, missing both legs, he struggles to accept his new reality. He can no longer walk, which means he can no longer fight.

From scratch.

No-one comes in peace. Every being in the galaxy wants something, and is willing to take it by force. The Hedalt were no different. They came from the distant reaches of the galaxy to wage war.
