Sentinel was established in 2003 as a dedicated conservative imprint within Penguin Group. It publishes a wide variety of right-of-center books on subjects like politics, history, public policy, culture, religion, and international relations. The name Sentinel symbolizes a tough-minded defense of America’s fundamental values and national interests.
Some of Sentinel’s most noteworthy bestsellers include Do the Right Thing and A Simple Christmas by Mike Huckabee; A Patriot’s History of the United States by Larry Schweikart and Michael Allen; An American Son by Senator Marco Rubio; Unintimidated by Governor Scott Walker of Wisconsin; The Secret Knowledge by David Mamet; Keeping the Republic by Governor Mitch Daniels of Indiana; Roger Ailes: Off Camera by Zev Chafets; The Tyranny of Clichés by Jonah Goldberg; and George Washington’s Secret Six by Brian Kilmeade and Don Yaeger – a runaway New York Times bestseller for more than three months.
