Lowrie and Shen are the youngest people in the world after a virus causes global infertility. When it looks like the virus has mutated, becoming even more deadly, they alone are left to try to find a cure. If they fail, they will be the last surviving members of the human race, destined to watch their species go extinct. But how can two teenagers succeed where the great scientists have failed? It feels as though there is no hope for humanity until they discover a secret that turns their entire world upside-down.
