Since the original publication of Nudge more than a decade ago, the title has entered the vocabulary of businesspeople, policy makers, engaged citizens, and consumers everywhere. The book has given rise to more than 200 "nudge units" in governments around the world and countless groups of behavioral scientists in every part of the economy. It has taught us how to use thoughtful "choice architecture" - a concept the authors invented - to help us make better decisions for ourselves, our families, and our society.

The correspondence between Carrie Allsop and David Mayer reveals, piece by piece, the painful details of a devastating affair between their spouses. With each commiserating scratch of the pen, they confess their fears and bare their souls. They share the bewilderment over how things went so wrong and come to wonder where to go from here. Told entirely through the letters of two comforting strangers and those of two illicit lovers, Evidence of the Affair explores the complex nature of the heart. And ultimately, for one woman, how liberating it can be when it’s broken.

Life is hard enough for a teenage girl in 1950s suburbia without having a mother who may—or may not—be a witch. A single mother at that. Sure, she fits in with her starched dresses, string of pearls, and floral aprons. Then there are the hushed and mystical consultations with neighborhood women in distress. The unsavory, mysterious plants in the flower beds. The divined warning to steer clear of a boyfriend whose fate is certainly doomed.

Overworked and underappreciated, single mom Amy Byler needs a break. So when the guilt-ridden husband who abandoned her shows up and offers to take care of their kids for the summer, she accepts his offer and escapes rural Pennsylvania for New York City. Usually grounded and mild mannered, Amy finally lets her hair down in the city that never sleeps. She discovers a life filled with culture, sophistication, and - with a little encouragement from her friends - a few blind dates.

Finally, we are learning that simplicity equals sanity. We’re rebelling against technology that’s too complicated, DVD players with too many menus, and software accompanied by 75-megabyte “read me” manuals. The iPod’s clean gadgetry has made simplicity hip. But sometimes we find ourselves caught up in the simplicity paradox: we want something that’s simple and easy to use, but also does all the complex things we might ever want it to do.
