A young woman creates an imaginary friend to finally find peace from her worried parents. A theater actor loves his wife but still cheats on her. A father and daughter struggle to understand each other, yet their relationship blossoms as his death approaches. Eight stories about how people in our society try to connect with one another and the roles that hormones, genes, and social norms play in this. What attracts us to monogamy, and what to infidelity? How does friendship endure, and how does intimacy develop? Giovanni Frazzetto skillfully intertwines dramatic storytelling with the latest insights from biology and neuroscience, thus discovering love in a comprehensive new way.
