Aleksandr I. Solzhenitsyn’s startling book led, almost 30 years later, to Glasnost, Perestroika, and the "Fall of the Wall". One Day in the Life of Ivan Denisovich brilliantly portrays a single day, any day, in the life of a single Russian soldier who was captured by the Germans in 1945 and who managed to escape a few days later. Along with millions of others, this soldier was charged with some sort of political crime, and since it was easier to confess than deny it and die, Ivan Denisovich "confessed" to "high treason" and received a sentence of 10 years in a Siberian labor camp.

Most people think the way to write a best seller is to have a lot of talent and even more luck.

A best-selling author himself, and the author of the number-one best seller for writers, Plot & Structure, Mr. Bell has been teaching the principles of best-selling fiction for over 20 years, principles that apply to any genre or style.

Ancient Egyptian civilization is so grand our minds sometimes have difficulty adjusting to it. It lasted 3,000 years, longer than any other on the planet. Its Great Pyramid of Cheops was the tallest building in the world until well into the 19th century and remains the only Ancient Wonder still standing. And it was the most technologically advanced of the ancient civilizations, with the medical knowledge that made Egyptian physicians the most famous in the world.

Considered to the be one of most influential American authors, Howard Philip Lovecraft is synonymous with some of the best fantasy and horror fiction of the 20th century, second only to Edgar Allan Poe.

The Red Army had much to avenge when it finally reached the frontiers of the Third Reich in January 1945. Frenzied by their terrible experiences with Wehrmacht and SS brutality, they wreaked havoc - tanks crushing refugee columns, mass rape, pillage, and unimaginable destruction. Hundreds of thousands of women and children froze to death or were massacred; more than seven million fled westward from the fury of the Red Army. It was the most terrifying example of fire and sword ever known.

The ancient world has cast a long shadow, influencing our customs and religious beliefs, our laws, and the form of our governments. It has taught us when and how we make war or pursue peace. It has shaped the buildings we live and work in and the art we hang on our walls. It has given us the calendar that organizes our year and has left its mark on the games we play.

NASA's history is a familiar story, culminating with the agency successfully landing men on the moon in 1969. But NASA's prehistory is a rarely told tale, one that is largely absent from the popular space-age literature but that gives the context behind the incredible lunar program. America's space agency wasn't created in a vacuum; it was assembled from preexisting parts, drawing together some of the best minds the non-Soviet world had to offer.

Language defines us as a species, placing humans head and shoulders above even the most proficient animal communicators. But it also beguiles us with its endless mysteries, allowing us to ponder why different languages emerged, why there isn't simply a single language, how languages change over time and whether that's good or bad, and how languages die out and become extinct.
