That strange land, Maracoor—across the ocean from Oz—is beset by an invading army. In the mayhem, Rain and Cossy, a child felon, break out of prison. Helped by a few flying monkeys, they struggle to escape the city before it falls under siege. Their arresting officer, Lucikles, also retreats with his family to a highland redoubt. Cued in by secrets known only to the most highly placed members of the royal court, Rain and her companions hunt the fabled Oracle of Maracoor for guidance and soothsaying. Rain has to recover her forgotten past if she is to consider returning home. Cossy, the ten-year-old convicted of murder, must become invisible to avoid being taken into custody again. Meanwhile, the Fist of Mara, an arcane artifact that renders all around it barren, hammers against human lives.
