Aru Shah Series Books 1 - 5 Collection by Roshani Chokshi:

Aru Shah and the End of Time:
Twelve-year-old Aru Shah has a tendency to stretch the truth in order to fit in at school. Whilst her classmates are jetting off to exotic locales, she'll be at home, in the Museum of Ancient Indian Art and Culture where her mother works. Is it any wonder that Aru makes up stories about being royalty.

Aru Shah and the Song of Death:
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.

Aru Shah and the Tree of Wishes:
War between the devas and the demons is imminent, and the Otherworld is on high alert. Aru Shah and her friends are sent on a mission to rescue two targets, one of whom is about to utter a prophecy that cannot reach the ears of villainous the Sleeper.

Aru Shah and the City of Gold:
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's biggest question, though, is why every adult she has loved and trusted so far has failed her.

Aru Shah and the Nectar of Immortality:
Aru only has until the next full moon to stop the Sleeper from gaining access to the nectar of immortality, which will grant him infinite power. Her quest will have the Pandavas calling on old friends, meeting new allies, and facing fearsome trials, like...performing in a rock concert?
