In 2132 AD, fifteen-year-old Kassiana's life was royalty. Born on Nemal, the richest of the Paradise Planets, she had no idea how the people of Earth-the Gaians-suffered. But her idyllic and harmonious life was shattered when she was forcefully kidnapped and taken to live among them on a flooded Earth. There, the Gaians were divided by their assigned star scores, surviving on meager food rations, and under the constant threat of sonic beatings from the U.N.O.E. mediation officers. Singing in nearly-fluent Evéik to power up their wetsuits, Gaians contended against each other in the Siren Games-the foremost sporting competition in all the worlds-just to win a passport and be allowed entry to a Paradise planet. Now fallen from Paradise, worlds away from home, and with an increasing realization that no rescue is coming, Kassi must learn to survive as the lowliest of the Gaians and find some way to win the Siren Games-her only hope of ever seeing home again.
