On a fringe planet, Sever Squad makes a last, desperate effort to destroy a deadly horde before it can consume the galaxy.
After licking their wounds, Sever Squad gets a tip telling them to pick up their rifles, their swords, and their ship: the last chance to stop a super soldier project has arrived. Aurora and the other Severs head out to make good on her promise to catch and, if necessary, kill the agent behind it all.
That agent, though, has friends. Sever's old employers see promise in the super soldiers, a chance to take firm control over the galaxy. To get to the agent, Sever's going to have to get through their former friends.
Aurora always believed in fighting for cash, but nobody's paying Sever this time. This last mission? It's personal.
