Twelve-year-old Aru Shah has a tendency to stretch the truth in order to fit in at school. While her classmates are jetting off to family vacations in exotic locales, she'll be spending her autumn break at home, in the Museum of Ancient Indian Art and Culture, waiting for her mom to return from her latest archeological trip. Is it any wonder that 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 her claim that the museum's Lamp of Bharata is cursed, and they dare Aru to prove it. Just a quick light, Aru thinks. Then she can get herself out of this mess and never ever fib again. But lighting the lamp has dire consequences. She unwittingly frees the Sleeper, an ancient demon whose duty it is to awaken the God of Destruction. Her classmates and beloved mother are frozen in time, and it's up to Aru to save them. The only way to stop the demon is to find the reincarnations of the five legendary Pandava brothers, protagonists of the Hindu epic poem, the Mahabharata, and journey through the Kingdom of Death. But how is one girl in Spider-Man pajamas supposed to do all that?

Aru is only just getting the hang of this whole Pandava thing when the Otherworld goes into full panic mode. The god of love's bow and arrow have gone missing, and the thief isn't playing Cupid. Instead, they're turning people into heartless fighting-machine zombies. If that weren't bad enough, somehow Aru gets framed as the thief. If she doesn't find the arrow by the next full moon, she'll be kicked out of the Otherworld. For good. But, for better or worse, she won't be going it alone. Along with her soul-sister, Mini, Aru will team up with Brynne, an ultra-strong girl who knows more than she lets on, and Aiden, the boy who lives across the street and is also hiding plenty of secrets. Together they'll battle demons, travel through a glittering and dangerous serpent realm, and discover that their enemy isn't at all who they expected.

War between the devas and the demons is imminent, and the Otherworld is on high alert. When intelligence from the human world reveals that the Sleeper is holding a powerful clairvoyant and her sister captive, 14-year-old Aru and her friends launch a search-and-rescue mission. The captives, a pair of twins, turn out to be the newest Pandava sisters, though, according to a prophecy, one sister is not true. During the celebration of Holi, the heavenly attendants stage a massage PR rebranding campaign to convince everyone that the Pandavas are to be trusted. As much as Aru relishes the attention, she fears that she is destined to bring destruction to her sisters, as the Sleeper has predicted. Aru believes that the only way to prove her reputation is to find the Kalpavriksha, the wish-granting tree that came out of the Ocean of Milk when it was churned. If she can reach it before the Sleeper, perhaps she can turn everything around with one wish. Careful what you wish for, Aru . . .

Aru Shah and her sisters—including one who also claims to be the Sleeper's daughter—must find their mentors Hanuman and Urvashi in Lanka, the city of gold, before war breaks out between the devas and asuras. Aru has just made a wish on the tree of wishes, but she can't remember what it was. She's pretty sure she didn't wish for a new sister, one who looks strangely familiar and claims to be the Sleeper's daughter, like her. Aru also isn't sure she still wants to fight on behalf of the devas in the war against the Sleeper and his demon army. The gods have been too devious up to now. Case in point: Kubera, ruler of the city of gold, promises to give the Pandavas two powerful weapons, but only if they win his trials. If they lose, they won't stand a chance against the Sleeper's troops, which will soon march on Lanka to take over the Otherworld. Aru's biggest question, though, is why every adult she has loved and trusted so far has failed her. Will she come to peace with what they've done before she has to wage the battle of her life?

Best-selling author Rick Riordan presents the breathtaking conclusion to Roshani Chokshi's New York Times best-selling Pandava quintet. Will the Sleeper gain immortality or be stopped once and for all? \*"Chokshi spins a fantastical narrative that seamlessly intertwines Hindu cosmology and folklore, feminism, and witty dialogue for an uproarious novel."—Kirkus Reviews (starred review of Aru Shah and the End of Time) 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.

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?
