'Since a deadly virus and the violence that followed wiped out his parents and most of his community, Finn has lived alone on the rugged coast with only his loyal dog Rowdy for company. He has stayed alive for two winters—hunting and fishing and trading food, and keeping out of sight of the Wilders, an armed and dangerous gang that controls the north, led by a ruthless man named Ramage. But Finn’s isolation is shattered when a girl runs onto the beach. Rose is a Siley—an asylum seeker—and she has escaped from Ramage, who had enslaved her and her younger sister, Kas. Rose is desperate, sick, and needs Finn’s help. Kas is still missing somewhere out in the bush. And Ramage wants the girls back—at any cost' (publication blurb).
