Excellent book to teach kids about chronic illness and friendship
"With autoimmune conditions becoming increasingly common, I found this book to be a wonderful resource for teaching my son that everyone’s body works differently. It opened the door to conversations about compassion, patience, and empathy, while understanding that a person’s challenges aren’t always visible. I really appreciated the opportunity to encourage kindness and how to become a supportive friend. The unique story and great illustrations kept my son engaged throughout."

Author FAQs
The Journey

What inspired you to write this book?
I’ve had the idea for A Beach Day with Peggy: Understanding Lupus since I was 8 years old. I actually wrote an early version of the story in my journal at that age. The book was inspired by my friendship with Spike, whom I met in first grade. She accepted my lupus without hesitation, and that kind of friendship made an enormous difference in my life.Because of her kindness and the support of the friends around me, I was still able to have a childhood that felt joyful and full. I went to the beach, swam, danced, went to birthday parties, and got to be a kid. This book is really rooted in that friendship and in the childhood memories that stayed with me from growing up in Tustin, California.
"A diagnosis can shape your life, but it does not define the limits of what your life can become."
What was it like growing up with lupus, from diagnosis to ongoing care?
I was diagnosed with lupus at age 5, after a trip to Disneyland, so a lot of my experience with the disease was shaped by how a child understands the world. I spent half of kindergarten and most of first grade at CHOC, the children’s hospital in Orange County.My mom, Gloria, was my caretaker through all of it. We passed the time making paper dolls and going to the hospital playroom for arts and crafts. Even now, Easter is still my favorite holiday because she promised me I would be home by Easter. I still remember coming back to a house filled with chocolate eggs and stuffed bunnies. That memory has stayed with me all these years. It reminds me how much my mom’s love and optimism carried me through those early days.

Did you know anyone else growing up with lupus? What was that like?
I did not know anyone else with lupus growing up, and that made it hard. I did not really have anyone my age who understood what I was going through, so a lot of the time I felt like I had to explain it in the simplest terms I could.I remember meeting other lupus patients in the hospital and realizing, even as a child, that lupus looks different for everyone. Some people have much more severe cases than others. For my classmates, I often simplified it by saying, “I’m allergic to the sun.” That became my way of explaining why I wore a big hat or put on sunscreen before recess.I think a book like this would have meant a lot to the 5-year-old version of me, who wanted answers in a language that felt understandable and comforting. My hope is that this story helps children and families talk about chronic illness in a way that feels gentle, relatable, and a little less scary.

What would you tell your younger self about managing lupus long term?
More than anything, I would tell my younger self that community matters. The people who love you, stand by you, and grow with you will help carry you through life’s hardest moments.Spike and the other friends who inspired the characters in this book are still in my life today. We have gone through so much together: college, marriage, children, divorce, grief, and all the turns life can take. Having those deep roots in friendship gave me strength, stability, and joy. It reminded me that even in the face of adversity, it is still possible to build a full and bountiful life.
You’ve participated in the UCSF lupus cohort study, as well as many lupus walks and support groups. What motivates you to stay involved, and how have you made time for it over the years?
Being part of the study has been deeply meaningful to me. I’m grateful for the opportunity to give back to the lupus community, especially because I know my medical history is unique.My mother always told me dreams are still worth chasing, no matter what obstacles stand in the way. A diagnosis can shape your life, but it does not define the limits of what your life can become.I wrote A Beach Day with Peggy: Understanding Lupus with one hope in mind: that it might one day sit on the shelf of a children’s hospital gift shop, where a child being admitted for lupus – or any autoimmune disease – might pick it up and feel a little less alone. And maybe, through this story, they might begin to believe that their life can still be full of friendship, wonder, and possibility.
