Kana's best friend is falsely imprisoned and her ex-boyfriend's heinous behavior remains unpunished. While plotting revenge, Kana takes a shine to a newly arrived human, Finn. When the Erbo rebels take over her planet, Belonia, Kana needs all her wits and muscle to save Finn, overcome her parents' prejudice, defeat the rebels, and achieve justice for her best friend and her people. Non-stop action ensues as Kana takes on the rebels, helped by the socially-marginalized Harkos and their improvised army, some high-powered plasma blasters, and inside knowledge of the floating islands in the Sea of Snails.
