On her 30th birthday, Yale-educated Zoe Greene was supposed to be married to her high-school sweetheart, pregnant with their first baby, and practicing law in Chicago. Instead, she's planning an abortion and filing for divorce. Zoe wants to understand why her plans failed--and to move on, have sex, and date while there's still time. As she navigates dysfunctional penises, a paucity of grammatically sound online-dating profiles, and her paralyzing fear of aging alone, she also grapples with the pressure women feel to put others first. Ultimately, Zoe's family, friends, incomparable therapist, and diary of never-to-be-sent letters to her first loves, and the rock band U2, help her learn to let go--of society's constructs of female happiness, and of her own.
