Mia, Laney, Betts, and Ginger, best friends since law school, have reunited for a long weekend as Betts awaits Senate confirmation of her appointment to the Supreme Court. Nicknamed “the Ms. Bradwells” during their first class at the University of Michigan Law School in 1979—when only three women had ever served full Senate terms and none had been appointed to the Court—the four have supported one another through life’s challenges: marriages and divorces, births and deaths, career setbacks and triumphs large and small. Betts was, and still is, the Funny One. Ginger, the Rebel. Laney, the Good Girl. And Mia, the Savant.

But when the Senate hearings uncover a deeply buried skeleton in the friends’ collective closet, the Ms. Bradwells retreat to a summer house on the Chesapeake Bay, where they find themselves reliving a much darker period in their past—one that stirs up secrets they’ve kept for, and from, one another, and could change their lives forever.
