Abby Gray is the author of Clayton Sparks Leaves His Mark and an advocate for organ donation. Abby’s husband, Reid Gray, received a directed donation liver transplant in January of 2019 from Clayton Sparks. After developing an amazing relationship with Clayton’s parents and learning what a kind and giving person he was, Abby was inspired to write a children’s book about him. Clayton Sparks Leaves His Mark encourages readers to find ways to “spark” kindness in others, and gently opens up the conversation of organ donation within families.
