About this book
Best friends Harry and Doug hit a rough patch when Harry develops a secret crush and suddenly isn’t interested in the usual recess mischief. Told from Doug’s warm, funny perspective, the story captures the everyday drama of second grade—notes, snowball fights, and changing friendships. Early chapter readers will relate to the classroom antics and the confusing feelings that come with growing up. Gentle humor and short chapters make it a confidence-building read for grades 1–3.
Setting: elementary school classroom and neighborhood in winter
