Harper and Lane lead a quiet and romantic life together in Cuba until world crisis calls Harper to leave the country and perform old tasks she has not yet overcome to save the country she has faithfully served for years, and perhaps years to come, while Lane toils at a bake shop, takes karate in her spare time, and loses what she thinks important to her. The two must find out what their partnership means to them when their relationship is given an ultimatum. In this thrilling futuristic novel, same-gender birth is just as plausible as an enchantress assassin taking out world leaders, leaving many openings for Harper and Lane to explore conventionalities and their own desires.
