Unbelievable: My Front-Row Seat to the Craziest Campaign in American History by Katy Tur, 291 pages.
Katy Tur was assigned to the Trump campaign by NBC News in early 2015. She followed the candidate around the country until November of 2016, reporting on Trump's angry, crazy, and improbable rise to the Presidency. Along the way she got to be attacked and praised personally by the candidate, depending on his mood. She was able to see and hear all of the headline grabbing antics of the candidate, from talking about his penis size at a debate, to veiled threats from the candidate towards the press-corp, so frequent and so effective at riling up the campaign crowds that Tur and many of the press following Trump around resorted to private security. An interesting read about an extraordinary time.
