Jumia Books Partypooper - Wimpy Kid 2026 New Book By Jeff Kinney

Editorial Reviews
Review
"Kinney dishes up a rich mixture of deadpan monologue and cartoons laden with gags and punchlines for this 20th series entry…A festive frolic―even if the frosting on the birthday cake does turn out to be mayonnaise."

―Kirkus Reviews
