Inspired by Envy's daughters, she writes books about their milestones. With each milestone, there comes a new challenge.
Envy found that books helped her daughter transition to school for the first time. The first time is always the scariest, but making it seem fun for a child can help them transition.
Envy incorporates subtle cultural representation in her book. It's important to her that children can relate to the characters in her books. Suab Zoo is Hmong-American student who learns how to make friends and express herself at school. She learns that school is fun!
