Hot on the heels of John Bolton’s behind-the-scenes look at the Trump White House, the president’s niece, Mary Trump, will be out next month with a family tell-all that’s said to contain “harrowing and salacious” details about her uncle, before and after his election.

The book’s title alone is enough to unnerve the president and other members of his extended family:

“Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man” is currently set for publication on July 28. Details have already started leaking.

Trump is already suing Bolton, though it remains to be seen if he can block publication of his former national security adviser’s book, due out next week.

And the Daily Beast reported Wednesday that Trump “has told people close to him that he’s getting his lawyers to look into the Mary Trump matter.”

The lawyers will “explore what could be done in the way of legal retribution — or at least a threat” against Mary Trump, “likely in the form of a cease and desist letter,” says the Beast, citing two people “familiar with the situation.”

Both Mary Trump’s book and Bolton’s — “The Room Where it Happened” — were already riding high on the Amazon sales charts on Wednesday, Bolton’s at No.1, Mary’s at No. 5.

In her book,” the Beast reported Wednesday, “Mary Trump is not only expected to discuss difficult internal family dynamics and offer revelations about a younger Donald Trump; she is also expected to out herself as a primary source behind a Pulitzer-winning New York Times investigation into her uncle’s taxes.”

Beast reporter Lachlan Cartwright, who broke the news of “Too Much and Never Enough” on Sunday, wrote that it will contain “harrowing and salacious stories” about the president.

Mary Trump’s publisher, Simon & Schuster, “declined to comment on any potential legal action,” the Beast says.
