A timely, powerful story of survival set in the not-too-distant future that Margaret Renkl (Late Migrations) calls "a beautiful book...shot through with such tenderness and humanity, such love and courage and beauty and hope, that it feels almost like a prayer."

With fires devastating much of America, Lark and his family first leave their home in Maryland for Maine. But as the country increasingly falls under the grip of religious nationalism, it becomes clear that nowhere is safe, not just from physical disasters but also persecution. The family secures a place on a crowded boat headed to Ireland, the last place on earth rumored to be accepting American refugees. Upon arrival, it turns out that the safe harbor of Ireland no longer exists either--and Lark, the sole survivor of the trans-Atlantic voyage, must disappear into the countryside. As he runs for his life, Lark finds two equally lost and desperate souls: one of the last remaining dogs, who becomes his closest companion, and a fierce, mysterious woman in search of her lost son. Together they form a makeshift family and attempt to reach Glendalough, a place they believe will offer protection. But can any community provide the safety that they seek?
