The little robot Sessé knows that light is evil. It reveals secrets, shows the prey to the predator, burns and scorches and sears. Sessé has spent all her life hiding from the light, huddling in darkness with her mother on their little island home. But one day, the light finally finds them. One day there are no shadows left to hide in, and Sessé and her mother must brave the light, learn to survive it--and, perhaps, even learn to love it.
