Friendship makes life worth living, and worth ending too. Eufrasia Vela is a caregiver—it’s not just her job. But when she begins working with Doña Carmen, a bedridden elderly woman who spends her days staring out the window at her now-obstructed view of the sea, she confronts the limits to her ability to help. That is, until Doña Carmen makes a big, last request: to transform her caretaking from helping her stay alive to helping her die. A good death has much in common with a good life, after all, and incapacity, loneliness, and isolation are devastations that a compassionate friend can help ease. Dignity, community, respect, and generosity—they’re what Eufrasia offers her clients, and what their friendship offers her. One Hundred Guinea Pigs is the lifegiving, warmhearted novel about euthanasia you didn’t know you needed.
