In Hearlight, twelve-year-old Kate is devoted to her scientist grandfather, and when he withdraws into round-the-clock work in his laboratory, she determines to draw him out of his solitude. Instead, he draws her into the world he has discovered, of PCL, or ''Pure Condensed Light'' a force, he says, that powers the universe.
When Kate and Grandfather learn that the sun is mysteriously and rapidly burning out, they determine to save it by journeying to the mysterious star Trethoniel, a source of PCL. Their dazzling trip to distant galaxies on the backs of giant butterflies, complete with terrifying monsters, otherworldly beings, and genuinely frightening space battles, climaxes in a bittersweet victory over the forces of darkness.
