We Are All Enlisted (Enlisted Book 1)

Peter Wright joined the Navy thinking that he could do his time in a nice, quiet billet somewhere on Earth. The Navy had other ideas. When the asteroid miners claimed their independence, Peter finds himself getting sent to space on a warship headed straight into the combat zone. He has to get used to everything: zero gravity, standing watch, and being the only Earth-born in his crew. And he has to be ready for the biggest battle the solar system has ever seen.
