Greyson McEntire thinks he is a nobody.
 
Despite being a decorated rock climber and scholar in the classroom, most of his high school peers don’t even know his name. Even his own mother can’t take a break from her work for long enough to care. If it wasn’t for his best friend, Colter, Greyson would be all alone. 
 
But that all changes when Greyson and Colter both get a mysterious invite from the National Interdisciplinary Notable Juveniles Association to a summer camp that promises to change their lives. Together, the friends dive into an adventure with the N.I.N.J.A.’s.
 
As they meet new friends, learn about secret history, and practice obstacle course training, a greater truth becomes apparent.
 
The N.I.N.J.A. organization isn’t only trying to educate the leaders of tomorrow…
 
It’s trying to save the world from a dark, sinister force.
