A heartwarming story about a little girl from Cameroon who discovers that confidence, curiosity, and kindness can carry her dreams as far as she dares to imagine.
By Alimatou M. Tchafa, PhD MBA and Maria Guadalupe Castaneda, PhD · Illustrated by Maria Guadalupe Castaneda, PhD

Erica Means Powerful is a heartwarming children's story about a little girl from Cameroon who learns to believe in herself with the love and guidance of her grandma and mom. Shy but curious, Erica discovers the joy of learning, the magic of nature, and the power of kindness.
As she grows, her dreams take her far. She becomes a scientist and travels to new places, caring deeply for the world around her.
Across 36 fully hand-illustrated pages, the story weaves together African cultural identity, intergenerational family bonds, STEM aspiration, and environmental stewardship — making it a meaningful addition to home libraries, early childhood classrooms, and school or public library collections.
Every illustration in the book was created entirely by hand by Dr. Castaneda, bringing the landscapes of Cameroon and the warmth of Erica's family to vivid life.




The character at the heart of this book is inspired by a real little girl: Erica, the daughter of co-author and AHA founder Dr. Alimatou Tchafa. Watching her daughter grow curious about the world sparked a question every parent of a young Black girl knows well: where are the books in which she can see herself dreaming big?
So Dr. Tchafa wrote one. Together with scientist, author, and illustrator Dr. Maria Guadalupe Castaneda, she created a story where a girl who looks like Erica grows up to become a scientist who cares for the world around her — because children cannot become what they cannot see.
