In their upcoming book, three House Republican leaders promise to provide a plan for leading the country out of the economic doldrums and into an era of prosperity, according to an official description that will be released Wednesday.

“This isn’t your grandfather’s Republican party,” reads the description that will appear on the back jacket of “Young Guns,” the new book by Minority Whip Eric Cantor (Va.), Chief Deputy Whip Kevin McCarthy (Calif.) and Rep. Paul Ryan (Wis.).

The summary says the three leaders are “proud Republicans” who believe the party has strayed from its core principles, including “economic freedom, limited government, the sanctity of life, and putting families first.”

“This groundbreaking book is a call to action that sets forth a plan for growth, opportunity, and commitment that will propel this country to prosperity once again,” it says. “Together, the Young Guns are changing the face of the Republican party and giving us a new road map back to the American dream.”

The description casts the authors as the leaders of the new Republican Party and assigns them each a specific role: “Cantor (the leader), Ryan (the thinker), and McCarthy (the strategist).”

“These Young Guns … are ready to take their belief in the principles that have made America great and translate it into solutions that will make the future even better, solutions that will create private sector jobs, maximize individual freedom, and establish a better world for our children,” the summary says.

The book is expected to be released in September, according to the website of publisher Simon and Schuster.
