A Q&A with Author Dr. Carrie Kollias

Why did you write Maria’s Marvelous Bones?

I got the idea for Maria’s Marvelous Bones nearly ten years ago when I was an orthopaedic trainee. Thousands of kids get fractures every year and I thought knowing what happens next would comfort them. As I now have my own kids, I also wanted to write a book that explained the science behind bone healing. Most children’s books about the body are quite dry and uninteresting to young readers, but my book draws them in through a narrative and educates them with accurate and age-appropriate information.


Gender and ethnic diversity within the healthcare professions is also a passion of mine. Orthopaedic surgery is the least diverse of all medical specialties. In the USA, only 6.1% of orthopaedic surgeons are women, and even less are visible minorities. In Maria’s Marvelous Bones, the triage nurse is male and the orthopaedic surgeon is a visible minority female. I hope that kids from all cultural and social demographics will read this book and set their sights on whatever career they wish. Maybe I will even get to work with one of them someday as a future orthopaedic colleague!

How do you feel Gill Guile’s illustrations enhance Maria’s Marvelous Bones?


I was very fortunate to work with Gill on this project. She is an experienced illustrator who understood my desire for medical accuracy as well as my goal of showing diversity in members of the healthcare team. Some of the characters in this book are real people, which she captured amazingly. I also gave Gill many pictures of medical equipment and even X-rays to ensure that her drawings were accurate reflections of how we treat kids with a similar injury. I love how cute these illustrations are and am still amazed by how she was able to capture personality, especially in Maria and Taso.
