"As could be expected in a book about introductory martial arts, there is solid messaging about working hard, facing your fears, and practicing without complaint that could lend to further discussion on character development. There is also very understated multigendered and multiracial representation among the campers...the coloring is full of wonderfully saturated rusts and blues, and the triumphant story is satisfying."
--Booklist
"Sharply metered, power-packed rhymes, many using onomatopoetic slams, bangs, chops, and kicks, suit the concept well...and the action-dense story is illustrated to enhance the text...an original take on the ninja theme in portraying a training camp and inter-camp challenge. There are plenty of page-turning twists throughout, with (no surprise) a happy ending for the young ninja stars."

"This book will absolutely speak to the kid who was born with a Bruce Lee poster above his crib. It's for the child who goes through life with kiai on his lips, and stealth in his step; and for the kid who needs the kind of confidence-boost that martial arts offers."---The Southern Illinoisan
"This rhyming story reads well and the stylized illustrations are colorful and fun."--Children'sBookwatch, the Midwest Book Review
The snappy, rhyming text will appeal to early readers and read-aloud audiences. A recommended purchase for any library, this book will have kids asking when they can enroll in Ninja Camp!---School Library Journal
