In this first book of a new illustrated middle grade series by a #1 New York Times-bestselling author, Marc learns to become a Warrior Kid after his uncle Jake, a Navy SEAL, comes to stay for the summer.



Fifth grade was the worst year of Marc’s life. He stunk at gym class, math was too hard for him, the school lunch was horrible, and his class field trip was ruined because he couldn’t swim. And the most awful thing about fifth grade? Kenny Williamson, the class bully, who calls himself the 'King of the Jungle.' When Marc's mother tells him that his Uncle Jake is coming to stay for the whole summer, Marc can't wait. Uncle Jake is a for real, super-cool Navy SEAL. And Uncle Jake has a plan. He's going to turn Marc into a warrior. Becoming a warrior isn’t easy. It involves a lot of pull ups, sit ups, pushups, squats, swimming, eating right, and studying harder than ever before! Can Marc transform himself into a warrior before school starts in the fall – and finally stand up to the King of the Jungle himself?
