Composition of Life: A Memoir of Science and Spirituality begins with a death, but through that ending, author Thane Kreiner, PhD, reveals deep connections within life that will help readers who are also on journeys of self-awareness and spiritual discovery. As Kreiner's mother dies from pancreatic cancer, Kreiner learns from her the power of full forgiveness, which sets him on a path through memories of growing up with an alcoholic and abusive father. Drawing on his background as a scientist, he begins to see evidence and proof in spirituality as well, and both help him along this journey. The stories in Composition of Life are rooted in history and connected with the #MeToo movement, racism in the United States, and climate change. Writing these essays led Kreiner to a place of forgiveness he never imagined was possible-something readers may find as well.
