It's shaping up to be a good year for Louise and her super-popular best friend Sienna Marshall. That is, until Louise's dad's 40th birthday party, when he gets caught cheating with Sienna's mom. The fallout from the party causes Louise's social status to take a spectacular nosedive: her friendship with Sienna is in ruins, her parents are an ongoing source of humiliation, and a workplace friendship is headed into tricky waters. Suitably melodramatic, filled with wry humor, and flawless in its portrait of a high-school milieu, Louise's topsy-turvy world is a wildly fun, if slightly bumpy, ride.
