A Day That Felt Too Big

Some days don't start out bad. They just... grow.

For Lily, today is one of those days, and it's getting bigger by the minute.

When everything feels too loud, too bright, and too much, Lily and her brother Noah discover an unexpected guide: Bubble, a magical being who leads them into the Bubble Realm... a world where feelings become visible and the heart holds the key to everything.

Together, Lily and Noah learn that what they feel inside isn't something to hide or fix. It's something to understand.

A Day That Felt Too Big is the first book in The Bubble Realm Series, a story for kids who feel deeply, think deeply, and are ready to discover just how powerful their inner world really is.

This book introduces young readers to emotional self-regulation, heart coherence, and the idea that what they feel inside actually matters.

• Sensitive and empathetic kids ages 9-13
