Former Rep. Liz Cheney’s upcoming tell-all is being described by her publisher as a “warning” about the threat to American democracy posed by former President Donald Trump and his allies.

Little, Brown and Company ​calls the book by Cheney, one of two Republicans on the House select committee that investigated Trump’s actions in connection with the Jan. 6, 2021 Capitol riot a “gripping first-hand account from inside the hall of Congress … by the House Republican leader who dared to stand up to it.”​

Cheney, the daughter of former Vice President Dick Cheney, lost her Wyoming congressional seat last August after her role on the committee drew the ire of Trump and he backed a primary challenger against her. 

“The last two years have shown us once again that our constitutional republic is not self-sustaining,” Cheney​ ​said in a statement to Axios.

“It survives only because of the courage and honor of individual Americans. When history looks back on this time, each elected official will have to answer the questions: Did we do our duty? Were we faithful to our oath of office?”​ added Cheney, who calls herself a “constitutional conservative.” 

​The book, “Oath and Honor. A Memoir and a Warning,” will hit bookshelves Nov. 14, ahead of a potential 2024 presidential run.

The publisher told Axios Cheney’s tome “will take readers inside the rooms where congressional leaders grappled with the threat posed by Trump’s efforts to overturn the election​. She will detail lessons learned — stories of leadership, of cowardice, and of courage.”

“Cheney will explain why she decided to stand almost alone against her party; why she risked her career, her seat, and her position in leadership to do what she knew was right​.”
