About Rosalina The Author

Hello, I’m Rosalina Rangel, writer and creator of Hanna’s Universe! I am also a teacher with over ten years of experience in Mathematics and Physics education. Throughout my career, I have supported children and teenagers not only academically, but also emotionally, blending rigor, creativity, and empathy to guide them through their learning journeys.

I am deeply passionate about multilingual education, art, and emotional development. Having lived in Colombia, Brazil, Chile, Canada, the United States, and Mexico, I have experienced firsthand how language, culture, and identity shape the way we learn, feel, and connect with the world. These experiences strongly influence my work and inspire me to create stories that bridge cultures, emotions, and imagination.

As a Christian educator and writer, my faith shapes the way I understand learning, care, and hope. Hanna’s Universe was created from a desire to offer more than books — to build a meaningful world where children, families, and educators can find support through learning, faith, and creativity. Through devotionals, vocabulary books, coloring books, and future projects for parents, this universe is designed to grow alongside its readers. Guided by values such as solidarity, responsibility, commitment, and spiritual strength, my work seeks to create gentle spaces where learning becomes an act of love, and growth is embraced with intention.
