With dramatic flair, Jeff Guinn delivers the definitive portrait of Bonnie and Clyde. These media-savvy outlaws appealed to America's Depression-era hunger for swashbuckling characters. Glowing radio and newspaper reports transformed these "public enemies" into celebrities - much like the cinema gangsters of the time.

Nothing Like It in the World is the story of the men who built the transcontinental railroad. In Ambrose's hands, this enterprise comes to life. The U.S. government pitted two companies - the Union Pacific and the Central Pacific railroads - against each other in a race for funding, encouraging speed over caution. As its peak the work force approached the size of Civil War armies, with as many as 15,000 workers on each line. The surveyors, the men who picked the route, lived off buffalo, deer, and antelope.

Marc Headley provides an insider's view of life as a member of Scientology's "Sea Organization". Marc worked at Scientology's secret desert compound, which houses all Scientology management, for 15 years. The 500-acre property is located deep in the California desert.

Four years after that meeting, Nick Brokhausen and Jeff Miller leave the service within a few weeks of each other and begin an odyssey that takes them to dozens of countries on five continents.

Rose George, acclaimed chronicler of what we would rather ignore, sails from Rotterdam to Suez to Singapore on ships the length of football fields and the height of Niagara Falls; she patrols the Indian Ocean with an anti-piracy task force; she joins seafaring chaplains and investigates the harm that ships inflict on endangered whales. Sharply informative and entertaining, Ninety Percent of Everything reveals the workings and perils of an unseen world that holds the key to our economy, our environment, and our very civilization.

With an executive order from President Franklin Roosevelt in 1941, the United States Marine Corps - the last all-white branch of the U.S. military - was forced to begin recruiting and enlisting African Americans. The first black recruits received basic training at the segregated Camp Montford Point, adjacent to Camp Lejeune, near Jacksonville, North Carolina.
