In the Christian Republic, homosexual people are given two choices—a camp to "fix" them, or exile to the distant islands populated by lesbians and gay men.

Sixteen-year-old Jason chooses exile and expects a hardscrabble life but instead finds a thriving, supportive community. While exploring his identity as a transgender boy he also discovers adventure: kraken attacks, naval battles, a flying island built by asexual people, and a daring escape involving glow-in-the-dark paint. He also has a desperate crush on Sky, a spirited buccaneer girl, but fear keeps him from expressing his feelings.

When Jason and his companions discover the Republicans are planning a war of extermination, they rally the people of the Rainbow Islands to fight back.

Shy, bookish Jason will have to find his inner courage or everything and everyone he loves will be lost forever.
