A Gingrich has one of the top-selling books in the country, but it’s not Newt.

His wife, Callista, released her first children’s book, “Sweet Land of Liberty,” Monday, and it has jumped to No. 3 on the Amazon Best Sellers  list.

The children’s book features Ellis the Elephant, who comes to America and shares with children the story of America’s exceptionalism, a theme Newt Gingrich has articulated throughout his campaign for the Republican presidential nomination.

Leading the Amazon Best Sellers  list is “Killing Lincoln: The Shocking Assassination that Changed America Forever,” by Bill O’Reilly and Martin Dugard, followed by “Heroes of Olympus, the Book Two: The Sun of Neptune.”

Rounding out the top five are “Diary of a Wimpy Kid: Cabin Fever” by Jeff Kinney and “The Best of Me” by Nicholas Sparks.

At CPAC this weekend in Florida, a life-size Ellis the elephant joined Callista Gingrich while she talked about her book.

This is Callista’s first venture in children’s books, but the Gingrich couple has produced seven documentaries together. Throughout Newt Gingrich’s time on the campaign trail, the duo has fit in screenings of their documentaries at many stops. He has authored 23 books on his own, 13 of which have made the New York Times Best Sellers list.
