THE BIRTHDAY CASTLE

Kids learn teamwork when they launch a fort-building business.

When 8-year-old Caleb is $10 short for a special edition of a book from his favorite series, he enlists his best friend, Jax, to help him think up ways to earn the money. After the boys have a ball building a box fort, they decide to go into business creating forts for other kids (Jax needs money for a new soccer net). Some of the humor comes in the kids’ aping of adult language they don’t quite get: What’s an “odd job” anyway, and who hasn’t wondered if businesses use “Inc.” in their names just “to sound fancy”? In this way, the humor bolsters instead of competing with the seriousness with which the kids take their operation, empowering kids rather than laughing at them. To handle the business end, they recruit artistic Eddie (who’s saving up for a new brownie pan) to help with signs and marketing, and—when their big job, a box-fort castle for Analise’s birthday, is imperiled by Analise’s changing request—they bring professional Kiara on board. As their tight deadline looms, they adapt to unexpected obstacles and learn how to manage their team. On the cover, Caleb and Jax present white, and Eddie presents black; brown-skinned Kiara is South Asian. A glossary, discussion questions, and STEM activity add further heft; a cast of characters helps transitioning readers keep track.

Positive and upbeat.
