"Fans of heraldic silliness like "The Princess Bride" and "Shrek" will delight in ONCE UPON A TIM, a charming take on the traditional knightly adventure.-- "The New York Times Book Review"
"Budding heroes defeat class and gender expectations as well as the occasional monster in this wry outing."-- "Kirkus"
"The humor, enhanced by Quentin Blake-esque illustrations, will definitely find an audience with kids looking for a quick, funny read."-- "School Library Journal"
"Gibbs peppers his prose with entertaining side comments as well as "IQ boosters," explaining terms such as malodorous, iconoclast, and infinitesimal, while maintaining the pace of the narrative. This giddy romp through a medieval setting, complete with menacing trolls and gigantic, bloodthirsty butterflies, is the start of a promising series from the author of Spy School (2012) and its sequels."-- "Booklist"
"A comic quest follows, with scares and laughs abundantly on offer...Tim's chatty, entertaining narration, which includes ample potty humor and the occasional vocabulary 'IQ booster, ' also touches on lessons about stereotypes and unconscious bias throughout the chatty, madcap adventure." -- "Publisher's Weekly "
