The first title to publish in the series will be Elbow Grease, a picture book about a monster truck who is smaller than his four “brothers” but never gives up and displays the grit and determination to keep up with them.

The series was inspired by John Cena’s childhood, with Cena being the second oldest of five brothers.

“With Elbow Grease and the books to follow, I want to offer kids a fun and engaging way to learn about the power of ambition, dedication, and heart,” said Cena in the press release. “These concepts have been transformative in my life, from my childhood up to now, and it’s so important to me to pass the positivity on and help our youngest generation see that right mindset is key to achievement.”

Elbow Grease is illustrated by Howard McWilliam and is due out October 9th, 2018.
