In a starred review, Booklist's John Peters called Stuntboy, In-Between Time "equally funny and tumultuous", while Kirkus Reviews referred to it as "fun and emotionally perceptive".[1] Peters highlighted how "Reynolds adroitly weaves emotional business into the teeming tapestry of apartment houselife by surrounding his caped protagonist, still struggling with his parents’ recent separation, with a colorful cast depicted by Raúl the Third in typically snappy, dynamic flurries of motion on nearly every page."[2] Similarly calling the novel "humorous and exciting",Shelf Awareness's Natasha Harris wrote, "Reynolds's text is accessible, providing a quick, entertaining read that directly covers topics of divorce, friendship, and anxiety. Raúl the Third's digital illustrations enhance the superhero tone with loose, sketchy lines that show movement; intentionally chosen pops of color in the grayscale art focus the eye on important details."[3]
Also writing for Booklist, Ashley Young reviewed the audiobook narrated by Guy Lockard, Nile Bullock, Angel Pean, James Fouhey, and a full cast. Young highlighted Lockard's enthusiastic performance and noted that "the different voices will help young listeners follow along with the dialogue-driven story. The varying voices of the characters are backed by music and sound effects that give a comic-book feel to the story."[4]
In 2023, AudioFile named the audiobook one of the year's best audiobooks in the category of Children & Family Listening.[5] The following year, the Association for Library Service to Children included it on their list of Notable Children's Recordings.[6]
