President Donald Trumps estranged niece, Mary Trump, provides an unfiltered accountant of generations of toxic familial relations in her tell-all family memoir slated to be released July 14.

The book, Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man, published by Simon & Schuster, highlights the dysfunctional family that contributed to the president’s leadership style.

Mary Trump, 55, is the first Trump to reveal the family secrets, which include several unfavorable allegations against the president. Excerpts from the forthcoming memoir have been released to media outlets, in which Mary Trump claims that the president is a “sociopath” and that his learned “hubris and willful ignorance” are a danger to the country. She also alleges that the president acquired his “twisted behaviors,” from his toxic family, such as seeing other people in “monetary terms” and practicing “cheating as a way of life.”

Mary Trump claims that when the president was in high school, he enlisted someone to take the SAT, a pre-collegiate test, for him. His paid test taker helped him gain entrance, as an undergraduate, to one of the world’s most prestigious business programs, the University of Pennsylvania’s Wharton business school. The president frequently boasts about attending Wharton, calling it “super genius stuff,” describing it as “the best school in the world.”

Mary Trump also claims that while her father, the president’s eldest brother, Freddy Trump Jr., who was an alcoholic, was dying, the entire family decided to send him alone to the hospital. Freddy Trump Jr., 42, died alone in 1981 due to an alcohol-induced heart attack. She also alleges that the president went to see a movie the night his brother died.

Since late June, the Trump family, led by the president’s youngest brother Robert S. Trump, has been unsuccessfully trying to stop the book’s publication.

A New York appellate judge, Justice Alan D. Scheinkman, ruled on July 1 that Simon & Schuster could proceed with the memoir’s publication.

In his ruling, Scheinkman overturned a lower court’s decision that blocked the publication of the book.

The Trump family has sparred over whether Mary Trump violated a confidentiality agreement that the president’s father Fred Trump Sr. instituted as a central tenet in his will nearly 20 years ago.

Scheinkman is scheduled to rule on whether Mary Trump violated the agreement.

Scheinkman also found that Simon & Schuster was a third party entity, and therefore was not bound to the terms and conditions of the nondisclosure clause. “Unlike Ms. Trump,” Scheinkman wrote, “S&S has not agreed to surrender or relinquish any of its First Amendment rights.”
