Jetta’s home is spiraling into civil war. Le Trepas—the deadly necromancer—has used his blood magic to wrest control of the country, all while remaining a shadow, deep in hiding. And Jetta herself has been without treatment for her malheur for weeks. Though she’s never felt better, can she trust herself? Can she rely on her own mind? Leo, the young man Jetta’s in love with, along with Jetta’s brother and rebel leader Cam, head to the capital with a vial of Jetta’s blood, intent on infiltrating the palace, stopping the Boy King from deporting the Aquitans en masse, and finding Le Trepas. Meanwhile, Jetta will venture into the jungle with scientist Theodora to find supplies to make more of Jetta’s elixir. The source is in a temple dedicated to the Keeper of Knowledge, and there they find a monk who tells them Le Trepas stole the Book of Knowledge—and the Keeper’s soul—and hid it in Aquitan. Only Jetta can find and free it.
