The Daughter of Light has been kidnapped. Is the Son of Darkness her only hope? On Origo, little Lilink has been stolen away to the ash-covered ruin called Caligo. Different factions want her for their own purposes, including fulfilling the prophecy that would destroy the planet. And Jak is in pursuit. He and his brother Gray will let nothing stop them from finding Lilink. On their path, they encounter strange and powerful creatures who try to harm them during their relentless pursuit. But will a reunion between Jak and Lilink fulfill the terrible prophecy? Meanwhile, a war brews with Houses in the North, East, and West positioning their armies. Humans, dragons, trolls, and wolves must choose sides when an evil force starts a domino effect that could lead toward Origo's destruction. If the prophecy doesn't destroy Origo, will the coming world war bring the planet's end instead?
