Few journalists working today have covered Donald Trump more extensively than Maggie Haberman. And few understand him and his motivations better. Now, demonstrating her majestic command of this story, Haberman reveals in full the depth of her understanding of the 45th president himself, and of what the Trump phenomenon means.

Interviews with hundreds of sources and numerous interviews over the years with Trump himself portray a complicated and often contradictory historical figure. Capable of kindness but relying on casual cruelty as it suits his purposes. Pugnacious. Insecure. Lonely. Vindictive. Menacing. Smarter than his critics contend and colder and more calculating than his allies believe. A man who embedded himself in popular culture, galvanizing support for a run for high office that he began preliminary spadework for 30 years ago, to ultimately become a president who pushed American democracy to the brink.

The through-line of Trump’s life and his presidency is the enduring question of what is in it for him or what he needs to say to survive short increments of time in the pursuit of his own interests.
