by Rhoda Blumberg
Nonfiction · ages 8–12 · grades 3–7 · 790L

O

Picture book · ages 4–8 · grades K–3 · 620L

A sharp, unflinching look at a kid building a school-supply monopoly and discovering that hustle culture and friendship don't automatically go together—Flake writes dialect-forward and doesn't soften the girl's ambition or the mess she makes.
