Bibi Hossain was supposed to get her first kiss this summer.

Too bad her father finds out and grounds her for breaking his most arcane rule: No boys until your sister gets married.

Just when Bibi thinks she'll be stuck helping him at their popular fried chicken chain until school reopens, her oh-so-perfect older sister Halima drops a bombshell: she's marrying the heir of a princely estate turned tea garden in Bangladesh. Soon, Bibi is hopping on the next flight to Sylhet for Halima's Big Fat Bengali Wedding, hoping Abbu might even rethink the dating ban while they're there.

Unfortunately, the stuffy Rahmans are a nightmare--especially Sohel, the groom's younger brother. The only thing they can agree on is that their siblings are not a good match. But as the two scheme to break their siblings up, Bibi finds it impossible to stay away from the infuriatingly handsome boy.

Could her own happily ever after be brewing even as she stirs up trouble for her sister's engagement--or is there more steeping at the tea estate than Bibi knows?
