Twins imbued with incredible magic and near immortality will do anything to keep their family safe—even if it tears the siblings apart. Rhea and her twin brother, Lexos, have spent an eternity using cunning and magic to help rule their small, unstable country. Rhea controls the seasons to show favor to their most loyal stewards with bountiful harvests and short winters, while Lexos keeps the tides strong and impassable to maintain the country’s borders. Reigning over them both is their father, who holds dominion over death, using his most powerful weapon—fear—to keep the people, and his children, in line. Now, with an independence movement gaining ground, other nations jockeying for power, and their father’s iron grip weakening, the twins must take matters into their own hands to keep the world from crashing down around them.
