A rough and tumble tomboy, twelve-year-old Ariana couldn't be more different from her cousin Laila, who just arrived from Afghanistan with her family. Laila is a proper, ladylike Afghan girl, one who can cook, sew, sing, and who is well versed in Pukhtun culture and manners. Arianna hates her. Laila not only invades Ariana's bedroom in their cramped Fremont townhouse, but she also becomes close with Mariam Nurzai, Ariana's best friend.

Then a rival Afghan grocery store opens near Ariana's family store, reigniting a decades-old feud tracing back to Afghanistan. The cousins, Mariam, and their newfound frenemy, Waleed Ghilzai, must ban together to help the families find a lasting peace before it destroys both businesses and everything their parents have worked for.

"Senzai successfully weaves the dynamics of Afghan culture, history and political wranglings into a classically American mystery story (Kirkus Reviews)."
