In addition to being a 16-time world champion in pro wrestling, John Cena can add “New York Times Best Selling Author” to his long list of accolades. John Cena’s new book, Elbow Grease, has topped the New York Times’ Children’s Best Sellers list.

The picture-book about a little monster truck named Elbow Grease is the first installment of what will become a multi-part series. The synopsis from Amazon.com reads,

“Meet Elbow Grease, a little monster truck with a big problem! He’s smaller than his four brothers, but wants to prove that he has the guts and the grit to do big things. He decides that entering the Demolition Derby is the perfect way to show everyone that what he lacks in horsepower he makes up for in gumption. From multi-talented mega celebrity John Cena comes this exciting story about the importance of believing in yourself and never giving up. Full of high-octane illustrations and a new character kids will cheer for, this fun and fast-paced book proves that a little Elbow Grease . . . can go a long way!”

Cena has been doing the media rounds to promote the book release, including book signings across the country. He thanked everybody for making his dream of writing children’s books a reality and called this accomplishment a “truly surreal moment.”
