The storming of the Capitol on 6 January 2021 revealed the transition from President Trump to President Biden to be one of the most dangerous periods in American history, with the result of the election called into question by the sitting president.

But, as 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. At the highest level of the US military, secret action was taken to prevent Trump from possibly starting a war.

Woodward and Costa interviewed more than 200 people at the centre of the turmoil, resulting in a spellbinding and definitive portrait of a nation on the brink. They take readers deep inside the Trump White House, the Biden White House, the 2020 campaign, and the Pentagon and Congress, with vivid, eyewitness accounts of what really happened. Peril is supplemented throughout with never-before-seen material from secret orders, transcripts of confidential calls, diaries, emails, meeting notes and other personal and government records, making for an unparalleled history.

It is also the first inside look at Biden's presidency, revealing the background to his controversial decision to leave Afghanistan. He took office faced with the challenges of a lifetime: dealing with the continuing deadly pandemic and its crushing economic impact, all the while navigating a bitter and disabling partisan divide, and the hovering, dark shadow of the former president. 'We have much to do in this winter of peril,' Biden declared at his inauguration.

Peril is the extraordinary story of the end of one presidency and the beginning of another. The culmination of Bob Woodward's bestselling trilogy on the Trump presidency, along with Fear and Rage, it is an essential read for anyone wanting to understand this tumultuous period.
