Every time I write about my heart, I write about walking. Every time I write about walking, I write about my heart. What is it like to be born with a congenital heart defect? What does it mean to live knowing your heart will one day fail you? How do you walk without moving a muscle? In Pacemaker, poet David Toms deftly blends creative nonfiction, poetry and diary in an account of resisting, confronting, and living with a rare heart condition. His experience, including his hospitalisation during the Covid-19 pandemic, speaks to all of us in its exploration of what it means to live in a fragile yet resilient body, to walk multiple challenging paths, and to always a find a way to keep moving.
