Stranded on an alien world and recovering from injuries, Ethan longs to return to Earth and clear his name, but instead he finds himself navigating an unfamiliar alien society while managing a troublesome translator. To add to his troubles, his new home offers little peace as his contentious in-laws now live with his family. His trouble only increases when the Purg threaten his family once more and his father-in-law goes missing. Thankfully, Ethan has Jasper and his Yosimite teammates to rely on for support. With their help, he hopes he can protect those he loves.
