Dr. Kwane Stewart, founder of Project Street Vet and CNN's 2023 Hero of the Year, was a struggling veterinarian on the brink of burnout when a single, spontaneous act of kindness changed everything: offering free treatment to a homeless man's dog.

This powerful, honest memoir takes you onto the streets of California and beyond, revealing the extraordinary bonds of unconditional love between unhoused individuals and their animal companions. For people facing extreme loneliness and invisibility, a pet is their only family, their lifeline, and their bridge to stability.

In What It Takes to Save a Life, Kwane Stewart shows how healing these animals is a crucial step in recognizing the humanity of their owners. His journey is a profound reminder that we are all part of a wider community, and by extending compassion to our most vulnerable neighbors—and their beloved pets—we can save not just an animal, but a human soul.
