Another book that completely flopped but was said to be the hammer that would crush President Trump was Unhinged
by Omarosa. If you remember Omarosa was a White House staff member that Trump kindly hired after they meet while Trump was the host of the apprentice. Despite the constant kindness of the President, Omarosa kept breaking protocol and the rules of the White House to the point where she was eventually fired and barred from the property.
Jaded and angry with the President she wrote a book about the President that had only awful things to say about him and the first family, the media picked it up and gave her the starlight for a while. Only a few paid attention to the book and it ultimately failed horribly despite the media giving it the red carpet treatment.
