Harry Potter has never even heard of Hogwarts when the letters start dropping on the doormat at number four, Privet Drive. Addressed in green ink on yellowish parchment with a purple seal, they are swiftly confiscated by his grisly aunt and uncle. Then, on Harry's eleventh birthday, a great beetle-eyed giant of a man called Rubeus Hagrid bursts in with some astonishing news: Harry Potter is a wizard, and he has a place at Hogwarts School of Witchcraft and Wizardry. An incredible adventure is about to begin!

In the United States, teenagers can focus on one task for only sixty-five seconds at a time, and office workers average only three minutes. Like so many of us, Johann Hari was finding that constantly switching from device to device and tab to tab was a diminishing and depressing way to live. He tried all sorts of self-help solutions—even abandoning his phone for three months—but nothing seemed to work. So Hari went on an epic journey across the world to interview the leading experts on human attention—and he discovered that everything we think we know about this crisis is wrong.

We evolved to eat berries rather than bagels, to live in mud huts rather than condos, to sprint barefoot rather than play football - or did we? Are our bodies and brains truly at odds with modern life? Although it may seem as though we have barely had time to shed our hunter-gatherer legacy, biologist Marlene Zuk reveals that the story is not so simple. Popular theories about how our ancestors lived - and why we should emulate them - are often based on speculation, not scientific evidence. Armed with a razor-sharp wit and brilliant, eye-opening research, Zuk takes us to the cutting edge of biology to show that evolution can work much faster than was previously realized.

Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he's sure he'll be the first person to die there. After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he's alive - and even if he could get word out, his supplies would be gone long before a rescue could arrive. Chances are, though, he won't have time to starve to death. The damaged machinery, unforgiving environment, or plainold "human error" are much more likely to kill him first.
