When Peter awakes in the head of a girl, he is both delighted and alarmed that his secret yearnings have become reality. Very quickly, however, his error is apparent; this girl is not him. Kaitling –that’s her name– is twelve years old, like him. She’s the daughter of a magician, a prominent figure in another world. Boy and girl travel back and forth from each other’s minds but have little time to get acquainted before the island is overrun by warrior priests and she has to flee. At home, a conflict erupts when Peter is caught wearing his sister's clothes. He takes refuge at a friend's place. Meanwhile at school, a haughty new girl goads him about his girlishness and, spitting in his face, vows to rid the earth of him. The stage seems set for a desperate struggle to survive, but will ingenuity and youthful fervour be enough against folly and fanaticism?
