We are Sierra Luke. We write books for kids because we are kids. I'm 9 years old but don't worry our stories are great and we have hundreds of new ideas, so there will always be more stories from us.

My brother, my Mom and I are a real team. We work along with amazing illustrators, editors and narrators to bring the best stories. Stories that we love to read again and again.
