Poor Wagner—he is having a rough day. First, it’s April Fools’ Day and he is never sure whether people are fooling or telling the truth. Then, his best buddy Pearl chooses a different classmate to dance with at recess, leaving Wagner trying and failing to feel the beat. But finally, he turns his day around with a little April Foolery of his own. Controlled vocabulary, ample white space and familiar school setting add up to a treat for new readers who will recognize a little of themselves in sad-sack Wagner—and the joy he feels when he finally turns the tables on a bad day. Alley’s expressive animal faces are just right: Wagner’s wide mouse eyes tell every emotion and Pearl’s rabbit ears droop and straighten with her moods, giving new readers many visual cues that will help with decoding and enjoyment. Kids who love listening to Kevin Henkes’s books about Lily and her friends will enjoy reading this one themselves. (Early reader. 5-8)
