From #1 New York Times bestselling author and Fox News Channel's Chief Political Anchor, a captivating biography of Theodore Roosevelt, the stalwart naturalist, writer, ranchman, soldier, president, and avatar of our modern era.

There has never been a president like Theodore Roosevelt. An iconoclast shaped by fervent ideals, his early life seems ripped from the pages of an adventure novel: abandoning his place in the New York aristocracy, he was drawn to the thrill of the West, becoming an honorary cowboy who won the respect of the rough men of the plains, adopting their code of authenticity and courage. As a New York State legislator, he fought corruption and patronage. As New York City police commissioner, he walked the beat at night to hold his men accountable, and as New York governor, he butted heads with the old guard to bring fresh air to a state mired in political corruption. He was also an obsessive naturalist, conservationist, and hunter who collected hundreds of specimens of birds and animals throughout his life. He was a soldier and commander who led a regiment of "Rough Riders" to victory in the Spanish-American War, a show of leadership and bravery that put him on the national map. As president, he brought energy, laughter, and bold ideas to the White House, pursuing a vigorous agenda that established America as a leader on the world stage.

Meticulously researched and grippingly written, Bret Baier's exquisite book reveals the storied life of a leader whose passion, daring, and prowess left an indelible mark on the fabric of our country and reimagined the possibilities of the presidency.
