Here is Trump in action—how he runs his organization and how he runs his life—as he meets the people he needs to meet, chats with family and friends, clashes with enemies, and challenges conventional thinking. But even a maverick plays by rules, and Trump has formulated time-tested guidelines for success. He isolates the common elements in his greatest accomplishments; he shatters myths; he names names, spells out the zeros, and fully reveals the deal-maker's art. And throughout, Trump talks—really talks—about how he does it.

With his characteristic eyebrow-raising behavior, Richard P. Feynman once provoked the wife of a Princeton dean to remark, "Surely you're joking, Mr. Feynman!" But the many scientific and personal achievements of this Nobel Prize-winning physicist are no laughing matter. Here, woven with his scintillating views on modern science, Feynman relates the defining moments of his accomplished life.

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.

Vagabonding is about taking time off from your normal life - from six weeks to four months to two years - to discover and experience the world on your own terms.

When the obituary of legendary computer game architect Matthew Sobol appears online, a previously dormant daemon activates, initiating a chain of events that begins to unravel our interconnected world. This daemon reads news headlines, recruits human followers, and orders assassinations. With Sobol’s secrets buried with him, and as new layers of his daemon are unleashed, it’s up to Detective Peter Sebeck to stop a self-replicating virtual killer before it achieves its ultimate purpose - one that goes far beyond anything Sebeck could have imagined.

This is H.G. Wells at his best, delving into fantastic and strange worlds. The Time Machine, perhaps Wells' best known work, tells the story of the first time traveler. In the distant future the human race has evolved into two beings: the gentle Eloi and their dreaded cousins, the Morlocks, masters of the underworld.
