The transition from President Donald J. Trump to President Joseph R. Biden Jr. stands as one of the most dangerous periods in American history.

But as #1 internationally bestselling author Bob Woodward and acclaimed reporter Robert Costa reveal for the first time, it was far more than just a domestic political crisis. Woodward and Costa interviewed more than 200 people at the center of the turmoil, resulting in more than 6,000 pages of transcripts?and a spellbinding and definitive portrait of a nation on the brink.

This classic study of Washington takes readers deep inside the Trump White House, the Biden White House, the 2020 campaign, and the Pentagon and Congress, with eyewitness accounts of what really happened. Intimate scenes are supplemented with never-before-seen material from secret orders, transcripts of confidential calls, diaries, emails, meeting notes and other personal and government records, making Peril an unparalleled history. It is also the first inside look at Biden's presidency as he began his presidency facing the challenges of a lifetime: the continuing deadly pandemic and millions of Americans facing soul-crushing economic pain, all the while navigating a bitter and disabling partisan divide, a world rife with threats, and the hovering, dark shadow of the former president.
