Rikki and her sister, Linda, fell out with one another four months ago. They are not speaking when Linda emails that she has lethal abdominal tumors, that her only hope of survival is a total bone marrow replacement. Linda claims Rikki is too old to donate, and explains there’s only a slight chance she is a good match anyway—but Rikki refuses to accept that. Despite the wounding between them, Linda’s email ignites a wild aspiration in her sister: she will become the perfect donor, the perfect match, with the healthiest, most vigorous cells possible. She rises with intent to heal herself, her sister, and their rootlines, the patterns formed in their family of origin that have quietly shaped their lives. Rikki walks through the science while confronting dogma that limits how mind can transform body. She builds herself into a stem cell factory using Muay Thai kickboxing and vegetarian nutrition. Working through childhood wounds and mental limits with meditation and yoga, she finds her own power, as well as ways to show up for Linda and walk with her from the edge of death to a new life. Together, the two sisters beat the lymphoma—and, as they rediscover the intimacy and love of their innocent childhood, heal the intertwined roots of their family pain.
