One Hundred Guinea Pigs by Gustavo Rodríguez

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.
