Lotus Lowenstein's life is merde. She dreams of moving to Paris and becoming an existentialist. Yet here she is trapped in Park Slope, Brooklyn, with a New-Agey mom, an out-of-work dad, and a chess champion brother who dreams of being a rock star. Merci Dieu for Lotuss best friend, Joni, who loves French culture enough to cofound their high schools first French Club with Lotus. At the first meeting, the cutest boy in the world walks in. His name is Sean, and he too loves French culture and worships Jean-Paul Sartre.
At first, Lotus thinks Sean is the best thing to happen to her in years. Hes smart, cultured, and adorable. Unfortunately, though, Joni feels the same way. And having an existentialist view of love, Sean sees nothing wrong with enjoying both girls affections. Things come to a head when all three depart for Montreal with their teacher, Ms. G, on the French Clubs first official field trip. Will Sean choose Joni over Lotus? And will Lotus and Jonis friendship ever recover?
