According to Mashable, the book will follow Elbow Grease, a little Monster Truck who’s the runt of his mechanical litter and who feels out of place, especially compared to his four older brothers. The story will follow the tiny but mighty truck as he proves to everyone that he has “the guts, grit, and gumption to do big things.” The book is inspired by Cena’s own experiences, as he grew up with his four older brothers in West Newbury, Massachusetts. “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,” Cena told Mashable.“These concepts have been transformative in my life…so important to me to pass the positivity on and help our youngest generation see that right mindset is key to achievement.” According to a representative from Random House Children’s Books, Cena’s trademark “sense of humor and scrappiness,” will shine through enough for the books to be enjoyed by people of all ages. Despite what John Cena’s theme music may lead you to believe, the time for the release is not now: It’s set to hit shelves in October.
