With war looming, Emelin's plan involves breaking the Mother's bindings while her diplomacy-oriented friends persuade the world to join their rebellion. Their potential allies are wary of Emelin's connection to the feared Silent Death, unwilling to fight for a fae prince's puppet. Emelin and Creon, concealing their complex love, venture to a plague-cursed continent to learn more about the bindings. They encounter dragons, ruins, and dangerous forests while mistrust among the group escalates tensions. Their love could jeopardize their mission against the Mother, putting Emelin in a difficult position between her heart and duty. 'Ruins of Sea and Souls' is the third installment in the Fae Isles series, a mature adult fantasy romance saga.
