Lara is yet to turn fifteen and everything is already falling apart. It's a fight between life and death. A flare up of her illness has left her in the intensive care unit, spending the night that could be decisive alone. But Carmen, a doctor she's never seen before, is in the room, and she starts to tell her an exciting story, the story of life itself. An intense crossover novel that explains the concept of life. In the nineties we came to understand philosophy by reading 'Sophie's World'. Now, well into the twenty-first century, we will learn to better understand who we are and what we're doing here from three of the best scientists in their field.
