Edith Grossman's definitive English translation of the Spanish masterpiece. Widely regarded as the world's first modern novel, and one of the funniest and most tragic books ever written, Don Quixote chronicles the famous picaresque adventures of the noble knight-errant Don Quixote of La Mancha and his faithful squire, Sancho Panza, as they travel through sixteenth-century Spain. Unless you read Spanish, you've never read Don Quixote. "Though there have been many valuable English translations of Don Quixote, I would commend Edith Grossman's version for the extraordinarily high quality of her prose. The Knight and Sancho are so eloquently rendered by Grossman that the vitality of their characterization is more clearly conveyed than ever before. There is also an astonishing contextualization of Don Quixote and Sancho in Grossman's translation that I believe has not been achieved before. The spiritual atmosphere of a Spain already in steep decline can be felt throughout, thanks to her heightened quality of diction. Grossman might be called the Glenn Gould of translators, because she, too, articulates every note. Reading her amazing mode of finding equivalents in English for Cervantes's darkening vision is an entrance into a further understanding of why this great book contains within itself all the novels that have followed in its sublime wake." From the Introduction by Harold Bloom Miguel de Cervantes was born on September 29, 1547, in Alcala de Henares, Spain. At twenty-three he enlisted in the Spanish militia and in 1571 fought against the Turks in the battle of Lepanto, where a gunshot wound permanently crippled his left hand. He spent four more years at sea and then another five as a slave after being captured by Barbary pirates. Ransomed by his family, he returned to Madrid but his disability hampered him; it was in debtor's prison that he began to write Don Quixote. Cervantes wrote many other works, including poems and plays, but he remains best known as the author of Don Quixote. He died on April 23, 1616.

One of the most popular and beloved introductions to the concept of faith ever written, Mere Christianity has sold millions of copies worldwide. The book brings together C. S. Lewis legendary radio broadcasts during the war years, in which he set out simply to explain and defend the belief that has been common to nearly all Christians at all times. Rejecting the boundaries that divide Christianity many denominations, Mere Christianity provides an unequalled opportunity for believers and nonbelievers alike to absorb a powerful, rational case for the Christian faith.

A milestone in the history of popular theology, The Screwtape Letters is an iconic classic on spiritual warfare and the dynamics of temptation. This profound and striking narrative takes the form of a series of letters from Screwtape, a devil high in the Infernal Civil Service, to his nephew Wormwood, a junior colleague engaged in his first mission on earth, trying to secure the damnation of a young man who has just become a Christian. Although the young man initially looks to be a willing victim, he changes his ways and is "lost" to the young devil. Dedicated to Lewis's friend and colleague J. R. R. Tolkien, The Screwtape Letters is a timeless classic on spiritual conflict and the psychology of temptation which are part of our religious experience.

Both astonishing and prophetic, The Abolition of Man remains one of C. S. Lewis's most controversial works. Lewis sets out to persuade his audience of the ongoing importance and relevance of universal objective values, such as courage and honor, and the foundational necessity of natural law. He also makes a cogent case that a retreat from these pillars of our educational system, even if in the name of "scientism," would be catastrophic. National Review lists it as number seven on their "100 Best Nonfiction Books of the Twentieth Century."
