She longs for a home where her quiet son can grow strong, and a place where she can put down roots, even as Solvi’s ambition draws him back to Norway’s battles again and keeps her divided from her brother. As a growing rebellion unites King Harald’s enemies, Ragnvald suspects that some Norse nobles are not loyal to Harald’s dream of a unified Norway. He sets a plan in motion to defeat all of his enemies, and bring his sister back to his side, while Svanhild finds herself with no easy decisions, and no choices that will leave her truly free. Their actions will hold irrevocable repercussions for the fates of those they love and for Norway itself.
