"The text is easily accessible to young readers, with simple, repeating words, but also enforces ideas about controlling emotions and being responsible for one’s actions without being over-bearing. Children will easily relate to Penny and Benny as they grapple with sibling issues that are very real to this age group. The crafty charm of Hayes’s illustrations gives the book a timeless feel, while sleek panel variation and swooping action shots reestablish readers’s focus. Once again, Hayes has created a graphic novel that is inviting, relatable, but, most importantly, fun." --School Library Journal STARRED REVIEW
