“Humorously entertaining. . . subtly thought-provoking. . . . Pratchett’s Discworld books are filled with humor and with magic, but they're rooted in—of all things—real life and cold, hard reason.”—Chicago Tribune Bumbling wizard Rincewind and hapless tourist Twoflower have survived a host of misadventures . . . only to face annihilation as a red star hurtles towards the Discworld in this gloriously funny second installment in Sir Terry Pratchett’s Discworld series (also the second book in the Wizards collection) It’s just one of those days when nothing seems to go right—and a most inopportune time for the first tourist ever to set foot in Discworld—accompanied by the carnivorous Luggage—to extend his already eventful vacation, even if it’s not quite by choice. A monstrous red star is on a direct collision course with the Discworld and the future appears uncertain at best. Discworld needs a hero to save it from total destruction. Unfortunately, it’s got the bumbling Rincewind, still recovering from the trauma of falling off the edge of the world. The alternative couldn’t be much worse. . . . The Discworld novels can be read in any order, but The Light Fantastic is the second book in the Wizards collection. The other books in the collection include: The Color of Magic Sourcery Eric Interesting Times The Last Continent Unseen Academicals

Why is it so hard to make lasting changes in our companies, in our communities, and in our own lives? The primary obstacle is a conflict that's built into our brains, say Chip and Dan Heath, authors of the critically acclaimed bestseller Made to Stick. Psychologists have discovered that our minds are ruled by two different systems - the rational mind and the emotional mind—that compete for control. The rational mind wants a great beach body; the emotional mind wants that Oreo cookie. The rational mind wants to change something at work; the emotional mind loves the comfort of the existing routine. This tension can doom a change effort - but if it is overcome, change can come quickly. In Switch, the Heaths show how everyday people - employees and managers, parents and nurses - have united both minds and, as a result, achieved dramatic results: • The lowly medical interns who managed to defeat an entrenched, decades-old medical practice that was endangering patients • The home-organizing guru who developed a simple technique for overcoming the dread of housekeeping • The manager who transformed a lackadaisical customer-support team into service zealots by removing a standard tool of customer service In a compelling, story-driven narrative, the Heaths bring together decades of counterintuitive research in psychology, sociology, and other fields to shed new light on how we can effect transformative change. Switch shows that successful changes follow a pattern, a pattern you can use to make the changes that matter to you, whether your interest is in changing the world or changing your waistline.
