A critically acclaimed literary memoir braiding together environmental research and the personal journey of generational healing, grief, and chronic illness. Author Eiren Caffall is the inheritor of a family legacy of 200 years of genetic kidney disease and the mother of a child who may inherit that legacy. A literary memoir on loss, chronic illness, and generational healing, Caffall’s The Mourner’s Bestiary is also a meditation on grief and survival told through the stories of animals in two collapsing marine ecosystems—the Gulf of Maine and the Long Island Sound—and the lives of a family facing a life-threatening illness on their shores. The Gulf of Maine is the world’s fastest-warming marine ecosystem, and the Long Island Sound has been the site of conservation battles that predict the fights ahead for the Gulf.
