The author of Forever Undecided, Raymond Smullyan continues to delight and astonish us with his gift for making available, in the thoroughly pleasurable form of puzzles, some of the most important mathematical thinking of our time.
Voted America's Best-Loved Novel in PBS's The Great American Read Harper Lee's Pulitzer Prize-winning masterwork of honor and injustice in the deep South—and the heroism of one man in the face of blind and violent hatred One of the most cherished stories of all time, To Kill a Mockingbird has been translated into more than forty languages, sold more than forty million copies worldwide, served as the basis for an enormously popular motion picture, and was voted one of the best novels of the twentieth century by librarians across the country. A gripping, heart-wrenching, and wholly remarkable tale of coming-of-age in a South poisoned by virulent prejudice, it views a world of great beauty and savage inequities through the eyes of a young girl, as her father—a crusading local lawyer—risks everything to defend a black man unjustly accused of a terrible crime.
More than two hundred new and challenging logic puzzles—the simplest brainteaser to the most complex paradoxes in contemporary mathematical thinking—from our topmost puzzlemaster (“the most entertaining logician who ever lived,” Martin Gardner has called him). Our guide to the puzzles is the Sorcerer, who resides on the Island of Knights and Knaves, where knights always tell the truth and knaves always lie, and he introduces us to the amazing magic—logic—that enables to discover which inhabitants are which. Then, in a picaresque adventure in logic, he takes us to the planet Og, to the Island of Partial Silence, and to a land where metallic robots wearing strings of capital letters are noisily duplicating and dismantling themselves and others. The reader’s job is to figure out how it all works. Finally, we accompany the Sorcerer on an alluring tour of Infinity which includes George Cantor’s amazing mathematical insights. The tour (and the book) ends with Satan devising a diabolical puzzle for one of Cantor’s prize students—who outwits him! In sum: a devilish magician’s cornucopia of puzzles—a delight for every age and level of ability.
Caitlin misses her brother every day. Since his death in a school shooting, she has no one to explain the world to her. And for Caitlin, the world is a confusing place. She hates it when colours get mixed up, prefers everything to be black-and-white, and needs to check her Facial Expressions Chart to understand emotions. So when Caitlin reads the definition of "closure", she decides that's what she needs. And as she struggles to find it, a world of colour begins to enter her black-and-white life...
From Simon & Schuster, This Book Needs No Title is Raymond Smullyan's budget of living paradoxes—the author of What is the Name of This Book?

Best friends Lucy, Elena, and Michael are excited to see "To Kill A Mockingbird" on their summer reading list. But not everyone in their class shares the same enthusiasm. So they hatch a plot to get the entire town talking about Harper Lee's classic novel.
Some schools have honor codes. Others have handbooks. Themis Academy has the Mockingbirds. From the glossy pages of its admissions brochure, the prestigious Themis Academy appears perfect in every way: exceptional academics, extraordinary students, the kind of extracurriculars to make an Ivy League proud, and zero instances of student misbehavior. But this boarding school isn't as pristine as it appears. There's a dark underbelly to the perfect record the Themis administration flaunts. Student infractions are rampant, and it's up to a secret vigilante society, the Mockingbirds, to maintain order on campus--a responsibility their members take very seriously. Alex Patrick never thought she would need the Mockingbirds. But when she's date-raped by another student, she doesn't know where else to go. As much as she'd like to forget what happened, she can't escape the daily reminders of what went wrong that terrible night. Before she can summon the courage to take a stand, she'll have to accept that her battle for justice is not hers alone. Standing up for someone, especially yourself, is worth the fight.
Forever Undecided is the most challenging yet of Raymond Smullyan’s puzzle collections. It is, at the same time, an introduction—ingenious, instructive, entertaining—to Gödel’s famous theorems. With all the wit and charm that have delighted readers of his previous books, Smullyan transports us once again to that magical island where knights always tell the truth and knaves always lie. Here we meet a new and amazing array of characters, visitors to the island, seeking to determine the natives’ identities. Among them: the census-taker McGregor; a philosophical-logician in search of his flighty bird-wife, Oona; and a regiment of Reasoners (timid ones, normal ones, conceited, modest, and peculiar ones) armed with the rules of propositional logic (if X is true, then so is Y). By following the Reasoners through brain-tingling exercises and adventures—including journeys into the “other possible worlds” of Kripke semantics—even the most illogical of us come to understand Gödel’s two great theorems on incompleteness and undecidability, some of their philosophical and mathematical implications, and why we, like Gödel himself, must remain Forever Undecided!
