A "fascinating" ( Kirkus Reviews), lively, and hilarious examination of the big questions about love and sex from the perspective of the latest brain science. Philosophers, theologians, artists, and boy bands have waxed poetic about the nature of love for centuries. But what does the brainhave to say about the way we carry our hearts? In the wake of a divorce, science writer and single mother Kayt Sukel made herself a guinea pig in the labs of some unusual love experts to find out. In each chapter of this edgy romp through the romantic brain, Sukel looks at a different aspect of love above the belt. What in your brain makes you love someoneor simply lust after them? (And is there really a difference?) Why do good girls like bad boys? Is monogamy practical? How thin is that line between love and hate? Do mothers have a stronger bond with their children than their fathers do? How do our childhood experiences affect our emotional control? Fiercely honest and wonderfully funny, Sukel can offer no simple solutions for the curveballs love throws our way. But after reading this gimlet-eyed look at love, sex, and the brain, you'll never look at romance the same way again.
