Eleven-year-old Mimi Mackson comes from a big Indian American family: Dad's a renowned food writer, Mom's a successful businesswoman, and her three older siblings all have their own respective accomplishments. It's easy to feel invisible in such an impressive family, but Mimi's dream of proving she's not the least-talented member of her family seems possible when she discovers a contest at the new bakery in town. Plus, it'll start her on the path to becoming a celebrity chef like her culinary idol, Puffy Fay.

But when Mimi's dad returns from a business trip, he's mysteriously lost his highly honed sense of taste. Without his help, Mimi will never be able to bake something impressive enough to propel her to gastronomic fame.

Drawn into the woods behind her house by a strangely familiar song, Mimi meets Vik, a boy who brings her to parts of the forest she's never seen. Who knew there were banyan trees and wild boars in Massachusetts? Together they discover exotic ingredients and bake them into delectable and enchanting treats.

But as her dad acts stranger every day, and her siblings' romantic entanglements cause trouble in their town, Mimi begins to wonder whether the ingredients she and Vik found are somehow the cause of it all. She needs to use her skills, deductive and epicurean, to uncover what's happening. In the process, she learns that in life, as in baking, not everything is sweet. . . .
