Opposites That Aren't
Opposites That Aren’t is a bold, minimalist picture book series exploring contrasts that aren’t really opposites at all. Each book pairs familiar ideas; loud and quiet, big and small, fast and slow, and reveals how both can exist at the same time. Simple language, striking design, and thoughtful page turns invite children to discover that difference isn’t division... it’s balance.
