On Michael Wolff's FIRE AND FURY inside the Trump White House

Michael Wolff put together a controversial book which he believes is a reflection of life in "Trump's White House." The book, released on January 5, 2018 is currently a best-seller on Amazon and is also in high demand among media houses and even the congress.
Wolff came through this based on several interviews with senior White House staff over a period spanning between Trump's first one hundred to two hundred days in office.
The issue here is the intent behind the book. Is it one of the tools to attack Trump's administration or is an unnecessary hype to draw unusual attention to Trump's already loud administrative style? Better still, could it be Wolff's strategy of topping the charts?
