Aru Shah has a tendency to stretch the truth in order to fit in at her private middle school. While her classmates are jetting off to exotic vacations, she'll be spending her autumn break in the Museum of Ancient Indian Art and Culture that her mom curates. Is it any wonder Aru makes up stories about being royalty, traveling to Paris, and having a chauffeur? One day, three schoolmates show up at Aru's doorstep to catch her in a lie. They don't believe...

After fourteen-year-old Aru Shah and her friends fail to keep a prophecy from the Sleeper, they undergo a rebranding campaign to prove the Pandavas's trustworthiness, but Aru believes they need to focus on finding the Tree of Wishes before the Sleeper and stopping war between the devas and the demons.

The Pandavas call on old friends, make new allies, and face fearsome trials as they embark on a mission to stop the Sleeper from accessing the nectar of immortality, but ultimately Aru must decide who deserves immortality--the devas or the asuras--and an unexpected answer comes from an unexpected place.
