When Clio went to the Underworld to steal magic from the sorcerers of Chrysalis, she thought she was helping to protect her homeland. But instead she discovered Lir's most dangerous spells, and now her brother Bastian wants to use them against the powerful family of Ra. Clio and Lyra will have to stop him before he uses the charm, but Bastian is not their only problem. Chrysalis needs the shadow charms, and they want Lyra dead. And this time they will not trust the work to mercenaries. Lear's father is following him, and no magic can defeat the most dangerous sorcerer of the three worlds. Clio and Lear will have to look for enchantments in the deserts of Ra and in the dark corners of the Underworld, while escaping from the hunters who hunt them. To survive, they need magic, which is much more dangerous than the one they possess. If they fail, all the worlds will pay.
