Aru Shah and the nectar of immortality

The Pandavas only have until the next full moon to stop the Sleeper from gaining access to the nectar of immortality, which will grant him infinite power. But how can Aru, Mini, and Brynne hope to defeat him without their celestial weapons? The Sleeper and his army are already plundering the labyrinth, and the sisters can't even enter. Their quest to get in will have them calling on old friends, meeting new allies, and facing fearsome trials, like . . . performing in a rock concert? When the moment of confrontation finally arrives, it's up to Aru to decide who deserves immortality, the devas or the asuras. The most unexpected answer will come from a most unexpected place.
