Hi, I'm Cali! I've loved books since childhood and wished to share this enthusiasm with my children.

I'm French of Caribbean origin (Martinique, to be precise!) and grew up in Paris — but I now call Los Angeles home, where I live with my two young children. My passion for books stems from the musical board books I found in France. They had embedded sound buttons that babies and children pushed to hear songs and musical tunes. I wanted to offer the same pleasure to children in the English-speaking world. Thus, Cali's Books was born.
