Priya feels excited and nervous about planning a popstar karaoke party for her best friend Melissa. Priya loves coming up with party ideas, making to-do lists, and crafting invitations and decorations, but she doesn't know any of Melissa's dance friends who are coming to the party. Will they have fun? Will Priya fit in with them? And can Priya shake it all off and make the whole party shimmer?

Jitty of Slant Jaw Row has always survived by her wits in Clockwork India, scavenging scraps to build clever inventions that keep her family alive. But when her latest creation accidentally knocks out power to the entire city of Calcutta, British officers throw Jitty in jail, where she expects to die.

Yet almost as soon as she arrives, Jitty is visited by the young Duke of Calcutta, who is impressed by her skill with gears. He has a job to offer her: Help finish a powerful machine unlike anything the empire has ever seen.

Whisked into a world of glittering palaces, secret laboratories, and brilliant inventors, Jitty wonders if the duke is telling her the whole truth about his machine—and what will happen to her and her family if she doesn’t complete it.
