Jessica Tarlov, a 2006 Bryn Mawr College graduate who became the lone liberal voice on cable news' most-watched show, has a book coming out next month that traces her path from a Main Line history major to a Fox News panelist who fields death threats and presidential attacks while arguing for civil discourse.

"I Disagree: Winning Arguments Without Losing Friends," published by Random House ($30, 272 pages), hits shelves Tuesday, Sept. 15. The book is part memoir, part toolkit for navigating political disagreements without torching relationships.

"I believe fundamentally that we don't want to lose friends on a permanent basis," Tarlov told the Bryn Mawr College Bulletin in an interview published Aug. 23. "Life is longer than Donald Trump."

Tarlov majored in history at Bryn Mawr and once wrote a research paper on cheesesteak brand loyalties in Philadelphia. She went on to study political scandals at the London School of Economics, led research and trends analysis at Bustle Digital Group, and now co-hosts the podcast "Raging Moderates" with Scott Galloway alongside her role on "The Five."

That role puts her across the table from Dana Perino, Greg Gutfeld and Jesse Watters. President Trump has targeted her directly on social media and encouraged Fox to fire her. The New Yorker Radio Hour profiled her as "a lonely liberal" navigating that environment.

Tarlov said she wrote the book after years of people asking the same question: how does she do it? She described the current moment as "a complete crisis" in Americans' ability to communicate across differences, and said her goal is not to change minds but to open them.

She credits Bryn Mawr with shaping that approach. In the Bulletin interview, she said the college helped her cultivate the confidence to take "enormous, big swings," and called attending a women's college "counterculture in the coolest way." She returned to campus for her 20th reunion earlier this year, participating in an author talk alongside alumnae publishing work on subjects from archaeological digs to handling online abuse.

The question kept coming.

On criticism from Trump and Republican commentators, Tarlov said she takes a research-first approach: when opponents attack her style rather than her substance, she reads it as a concession that they cannot engage with her facts.

No local book event has been announced. Tarlov's first confirmed signing is a conversation with Galloway at 92NY in New York City on Wednesday, Sept. 16. "I Disagree" is available for pre-order through major retailers.
