Dave Neiwart, an investigative journalist and author based in Seattle, will visit Eagle Harbor Book Company to discus his latest book, “Alt-America: The Rise of the Radical Right in the Age of Trump.”

Neiwart will visit the Winslow bookstore at 6:30 p.m. Thursday, June 13.

Just as Donald Trump’s victorious campaign for the U.S. presidency shocked the world, the seemingly sudden national prominence of white supremacists, xenophobes, militia leaders, and mysterious “alt-right” figures mystifies many. But the American extreme right has been growing steadily in number and influence since the 1990s with the rise of patriot militias.

Following 9/11, conspiracy theorists found fresh life; and in virulent reaction to the first black U.S. president, militant racists have come out of the woodwork.

Nurtured by a powerful right-wing media sector in radio, TV, and online, the far right, Tea Party movement conservatives, and Republican activists found common ground. Figures such as Stephen Bannon, Milo Yiannopoulos, and Alex Jones, once dismissed as cranks, now haunt the reports of mainstream journalism.

Neiwert has been tracking extremists for more than two decades. In “Alt-America,” he provides a deeply researched and authoritative report on the growth of fascism and far-right terrorism, the violence of which in the last decade has surpassed anything inspired by Islamist or other ideologies in the United States.

The product of years of reportage, and including the most in-depth investigation of Trump’s ties to the far right, this is a crucial book about one of the most disturbing aspects of American society.

From New Republic: “Tracing the ebbs and flows of this far-right extremism in the United States over the last 20 years, Neiwert argues that white nationalist activity in the age of Trump is simply the latest flare-up of what he calls ‘Alt-America,’ or the segment of the American population that has fed on conspiracy theories, racist misinformation, and deep distrust of federal institutions for decades.”

Neiwart is the author of many books, including “Of Orcas and Men: What Killer Whales Can Teach Us” and “Strawberry Days: How Internment Destroyed a Japanese American Community.”

His reportage for MSNBC.com on domestic terrorism won the National Press Club Award for Distinguished Online Journalism in 2000, and he is also a contributing writer for the Southern Poverty Law Center.
