"This new entry in the TOON line of emerging-reader comics may be the most sophisticated yet...Although simple enough to keep brand-new and below-level readers in tow—and strengthen their vocabulary with contextual clues—this charming and playful Hawaiian fable will reveal deeper layers to more intuitive readers."
"The Shark King is straightforward but engaging, led by Johnson’s standout, classically influenced art."
"Johnson is a talented cartoonist, and this graphic novel, which works either as a read-aloud or as a step toward chapter books for young readers, offers a story especially appealing to boys who long to be just like Dad."
--The New York Times
"Set against a rocky shoreline and underwater scenes teeming with sea life, [Johnson's] characters gesture and move with smooth naturalism, displaying both distinct personalities and expressions from comical to noble."
"Sharks, superpowers, and the comic-panel format will initially lure in readers, but the subtext of bullying, parental separation, and self-discovery will stay with them long afterward."
--The Horn Book Magazine (starred)
"This new title is a terrific choice for both graphic novel and folklore collections."
--School Library Journal
"How can you possibly resist this? Every page has something beautiful, all expertly laid out for younger eyes."
