The number one New York Times best seller by Pulitzer Prize-winning historian David McCullough rediscovers an important chapter in the American story that's "as resonant today as ever" (The Wall Street Journal) - the settling of the Northwest Territory by courageous pioneers who overcame incredible hardships to build a community based on ideals that would define our country.

In Unfamiliar Fishes, Sarah Vowell argues that 1898 might be a year just as crucial to our nation's identity, a year when, in an orgy of imperialism, the United States annexed Hawaii, Puerto Rico, and Guam, and invaded Cuba and then the Philippines, becoming a meddling, self-serving, militaristic international superpower practically overnight. Of all the countries the United States invaded or colonized in 1898, Vowell considers the story of the Americanization of Hawaii to be the most intriguing.

When Pulitzer Prize-winning journalist Bill Dedman noticed in 2009 a grand home for sale, unoccupied for nearly 60 years, he stumbled through a surprising portal into American history. Empty Mansions is a rich mystery of wealth and loss, connecting the Gilded Age opulence of the 19th century with a 21st-century battle over a $300 million inheritance. At its heart is a reclusive heiress named Huguette Clark, a woman so secretive that, at the time of her death at age 104, no new photograph of her had been seen in decades.

The Smallest Tadpole’s War in the Land of Mysterious Waters is based on a true story, a family story. In early 1861, Florida was a rural frontier state that had joined the Union just 15 years before. Its population of 140,000 was by far the smallest of any of the states that formed the Confederacy. In the 1860s, a Northern newspaper referred to Florida as "the smallest tadpole in the dirty pool of succession."

Born to a pioneering family in Upstate New York in the late 1800s, Allene Tew was beautiful, impetuous, and frustrated by the confines of her small hometown. At eighteen, she met Tod Hostetter at a local dance, having no idea that the mercurial charmer she would impulsively wed was heir to one of the wealthiest families in America. But when he died twelve years later, Allene packed her bags for New York City. Never once did she look back.

In 1896, a Norwegian immigrant and mother of eight children named Helga Estby was behind on taxes and the mortgage when she learned that a mysterious sponsor would pay $10,000 to a woman who walked across America. Hoping to win the wager and save her family's farm, Helga and her teenaged daughter Clara, armed with little more than a compass, red-pepper spray, a revolver, and Clara's curling iron, set out on foot from Eastern Washington.

He wasn’t always the Great Showman. In fact, Phineas Taylor Barnum grew up in relative poverty with only his wits to help him along. When his father died, the 15-year-old boy entered the working world as a shopkeeper’s assistant. In leaps and bounds, he worked his way from assistant to shop owner, lottery office owner, and, eventually, entertainment promoter. The bulk of his career was focused on his beloved American Museum, where thousands of ticket holders flocked every day to look at the human oddities, stuffed animals, live whale, and American memorabilia.

The Three Graces of Val-Kill changes the way we think about Eleanor Roosevelt. Emily Wilson examines what she calls the most formative period in Roosevelt's life, from 1922 to 1936, when she cultivated an intimate friendship with Marion Dickerman and Nancy Cook, who helped her build a cottage on the Val-Kill Creek in Hyde Park on the Roosevelt family land. In the early years, the three women - the "three graces", as Franklin Delano Roosevelt called them - were nearly inseparable.

Millions of fans of Little House on the Prairie believe they know Laura Ingalls - the pioneer girl who survived blizzards and near-starvation on the Great Plains, and the woman who wrote the famous autobiographical books. But the true story of her life has never been fully told. Now, drawing on unpublished manuscripts, letters, diaries, and land and financial records, Caroline Fraser masterfully fills in the gaps in Wilder's biography.

Frederick Law Olmsted is arguably the most important historical figure that the average American knows the least about. Best remembered for his landscape architecture, from New York's Central Park to Boston's Emerald Necklace to Stanford University's campus, Olmsted was also an influential journalist, early voice for the environment, and abolitionist credited with helping dissuade England from joining the South in the Civil War. This momentous career was shadowed by a tragic personal life, also fully portrayed here.

In this incredible narrative, Erica Armstrong Dunbar reveals a fascinating and heartbreaking behind-the-scenes look at the Washingtons when they were the First Family and an in-depth look at their slave, Ona Judge, who dared to escape from one of the nation’s Founding Fathers. Born into a life of slavery, Ona Judge eventually grew up to be George and Martha Washington’s “favored” dower slave. When she was told she was going to be given as a wedding gift to Martha Washington’s granddaughter, Ona made the bold and brave decision to flee to the North, where she'd be a fugitive.

Between 1854 and 1930, more than 200,000 orphaned or abandoned children were sent west on orphan trains to find new homes. Some were adopted by loving families; others were not as fortunate. In recent years, some of the riders have begun to share their stories. Andrea Warren alternates chapters about the history of the orphan trains with the story of Lee Nailling, who in 1926 rode an orphan train to Texas.

American Empress is the best-selling history of the dramatic life of heiress Marjorie Merriweather Post, daughter of breakfast-cereal magnate C.W. Post, founder of the Postum Cereal Company.

Orphaned at a young age, Edith Stuyvesant Dresser claimed lineage from one of New York's best known families. She grew up in Newport and Paris, and her engagement and marriage to George Vanderbilt was one of the most watched events of Gilded Age society. But none of this prepared her to be mistress of Biltmore House. Before their marriage, the wealthy and bookish Vanderbilt had dedicated his life to creating a spectacular European-style estate on 125,000 acres of North Carolina wilderness.

Biographers have consistently credited her father, Bronson Alcott, for Louisa May Alcott's professional success, assuming that this outspoken idealist was the source of her progressive thinking and remarkable independence. But in this riveting dual biography, Eve LaPlante explodes those myths, drawing on unknown and unexplored letters and journals to show that Louisa's "Marmee", Abigail May Alcott, was in fact the intellectual and emotional center of her daughter's world. It was Abigail who urged Louisa to write, who inspired many of her stories, and who gave her the support and courage she needed to pursue her path.
