Since 2008, Peggy has blogged about family life and living with autism, after the University of North Texas Press published her first book, See Sam Run. The memoir chronicles the ups and downs of Sam's early childhood, before he was diagnosed with autism.  Sam was diagnosed in the 1990s, when autism was becoming widely known and better understood. The book's manuscript won the Mayborn Prize for Literary Nonfiction.

After the release of See Sam Run, Peggy collaborated with autism expert Shahla Ala'i-Rosales to write an autism parenting book. Reviewers call Responsible and Responsive Parenting in Autism: Between Now and Dreams a "first-stop, must-read" for parents, caregivers, and the professionals who support them.

Currently, Peggy is writing her third book on living with disability. Inspired by the Crip Camp documentary, she wondered what if Camp Jened also had book for parents?  After all, parents also need space to shift their roles from caregiver to ally as their child becomes an adult.

Parents launch those first battles for self-determination, battles that can feel unwinnable long before adulthood. Somehow, our society expects the people shouldering the responsibility of living with disability to be the ones that push back on its many barriers. Yet, if we change the world through our children, then their transition to adulthood can be a radical act. As parents and caregivers become allies, they help resist the arbitrary authority over what comes next in disabled lives. They, too, make the personal the political and recast social reality for all of us.
