Debut author Bromley stumbles with the wrapup to his self-referential story, closing with a weak “Where do you think he’ll turn up next?” Regardless, O’Byrne’s crocodile is a personable antihero—she underscores his disruptive nature by drawing him in a brash, aggressive style that contrasts mischievously with her soft, storybook duckling—and her integration of typography and action is consistently ingenious.

By breaking the barriers, cleverly crafted books such as OPEN VERY CAREFULLY challenge and engage the reader in a special way—and amuse parents at the same time.

Bright reds and yellows, active line work, and plenty of white space create high energy and allow for the croc to interact with text and with the audience. This bold book will be effective as a group read-aloud, but some of the jokes will work well one-on-one, allowing children time to explore what the crocodile does with story and text.

Pure fun.
