Just one year into Donald Trump's term as president, Michael Wolff told the electrifying story of a White House consumed by controversy, chaos and intense rivalries. Fire and Fury, an instant sensation, defined the first phase of the Trump administration; now, in Siege, Wolff has written an equally essential and explosive book about a presidency that is under fire from almost every side.

At the outset of Trump's second year as president, his situation is profoundly different. No longer tempered by experienced advisers, he is more impulsive and volatile than ever. But the wheels of justice are inexorably turning: Robert Mueller's 'witch hunt' haunts Trump every day, and other federal prosecutors are taking a deep dive into his business affairs. Many in the political establishment - even some members of his own administration - have turned on him and are dedicated to bringing him down. The Democrats see victory at the polls, and perhaps impeachment, in front of them. Trump, meanwhile, is certain he is invincible, making him all the more exposed and vulnerable. Week by week, as Trump becomes increasingly erratic, the question that lies at the heart of his tenure becomes ever more urgent: Will this most abnormal of presidencies at last reach the breaking point and implode?
