According to Amazon's online description of the new book, "Now free from the constraints of running, Hillary takes you inside the intense personal experience of becoming the first woman nominated for president by a major party in an election marked by rage, sexism, exhilarating highs and infuriating lows, stranger-than-fiction twists, Russian interference, and an opponent who broke all the rules."
"She lays out how the 2016 election was marked by an unprecedented assault on our democracy by a foreign adversary," the blurb goes on to say. "By analyzing the evidence and connecting the dots, Hillary shows just how dangerous the forces are that shaped the outcome, and why Americans need to understand them to protect our values and our democracy in the future."
"In the past, for reasons I try to explain, I've often felt I had to be careful in public, like I was up on a wire without a net. Now I'm letting my guard down," wrote Hillary in the book's introduction.
The book is expected to focus on how alleged Russian interference and the testimony of then-FBI Director James Comey cost her the election, along with lesser factors such as sexism and misogyny.
"She wants the whole story out there from her own perspective. I think a lot of people are going to be really surprised by how much she reveals," said an anonymous source close to Clinton to The Hill. They added that the book will be a "bombshell."
"What Happened" is available for preorder on Amazon.
