The Scientific American Book of Love, Sex and the Brain: The Neuroscience of How, When, Why and Who We Love by Judith Horstman. Released 12/27/2011.
Publisher's Description: Who do we love? Who loves us? And why? Why does some love die while other love lasts? Is it really a mystery—or can the latest neuroscience shed some light on how, why, and whom our brains love? Horstman takes us on a tour of the brain and our many kinds of love—the whole smorgasbord of emotions, including the love of parent and child, the affectionate love of companionship, the passion of erotic love, the role of animals in our lives, and the love of God. She explains why love is good for our brains, how we're hardwired to crave the companionship of others—and how badly things can go without love.
