The Cardboard Kingdom #[nn]

A joyful gang of kids bursts from a cardboard-box fortress on Chad Sell's wonderfully energetic cover, each child wearing imaginative DIY costumes — crowns, helmets, a cardboard sword, a hook hand, a snake accessory — radiating pure creative energy and friendship. Sell's bright, cartoon linework captures exactly the kind of neighborhood adventure that feels both timeless and utterly alive. This 2018 Alfred A. Knopf release looks like a heartfelt celebration of imagination, play, and the magic kids can conjure from nothing more than a cardboard box.
