For Dee Kwan, every day is the perfect day. No, really. She has a house she loves, a job she adores, and a ridiculously attractive “nemesis” who never seems to mind when she wins their favorite online game. How can life possibly get better? (It can’t, obviously. It can only get much, much worse.) Soon Dee is forced to share her adorably cozy home with her parents and estranged grandmother. Then she’s tossed into the deep end at work, tasked with cleaning up a scandal for the intimidatingly chic luxury fashion firm Celeste. If that weren’t enough, she discovers her hot nemesis works there, too.

It’s considered a given, once your child hits puberty, that she or he will become uncommunicative, rude, and withdrawn, but there are neurobiological, social, and developmental reasons for these often-frustrating behaviors, and understanding those factors can really help us parent well.

The brain is a marvelous and complex organ that takes decades to fully mature, and no stage in that long process is more critical than the one we call the “toddler” years. During this period—from about one year old to three years old—a child transforms from a helpless infant into a running, chatting, insatiably curious little person with distinctive traits and interests. So, what is happening in the brain during this metamorphosis? How do humans acquire the motor, linguistic, and social skills that define this vital childhood period? Lise Eliot offers answers to these intriguing questions.

World War II is the defining conflict of the 20th century, one that created a line in the sands of history dividing the pre-war and post-war eras. In this epoch-defining conflict lies another definitive moment: the invasion of a 50-mile stretch of coast in Normandy, France, on June 6, 1944. This battle, also known as D-Day, was the pivot point of the war in Europe. Its success led to a nearly yearlong, bloody campaign that saw the liberation of France, Luxembourg, Belgium, and the Netherlands, followed by the final defeat of Hitler’s Third Reich.
