Guido and Vincent are childhood best friends—third cousins, really—living in Cambridge and dreaming about their futures. Guido plans to write poetry while Vincent feels confident he will win a Nobel Prize for physics. When Guido spots Holly while exiting a museum, he can immediately sense that she is difficult, quirky, and hard to live with—it’s love at first sight. Vincent, open-minded and cheerful, meets Misty at work. Though she is bored and misanthropic, he finds himself desperate to know her. Through courtship, jealousy, estrangement, and other perils, Tantas días felices follows four sane, intelligent, and good-intentioned people who manage to find love in spite of themselves.
