At thirteen, Albert Espinosa was diagnosed with cancer, something that changed his life forever. At fourteen, his left leg had to be amputated. At sixteen, his left lung was removed, and he was eighteen when part of his liver was removed. When he was finally told he was cured, after ten years in and out of hospitals, Albert realized he had learned a lesson from the disease: the sad thing is not dying, but not knowing how to live. Albert Espinosa never wanted to write a book about cancer. Instead, he wrote a book about the yellow world. What is the yellow world? It's a world the color of the sun, within everyone's reach. It's the name of a way of living, of seeing life, of nourishing oneself with the lessons learned in good times as well as bad. It's the world that makes you happy. The yellow world has no rules; it's made of discoveries. Albert Espinosa won several battles against death, and that's why his stories are so full of life. He's powerful because he never gives up. And, as a last resort, he negotiates: he traded a leg and a lung for his life. He learned to lose in order to win. And his greatest hope is that, after reading this book, you'll set out in search of your yellow world.
