Years ago, in the 2000s, someone handed me a novel about the journey of a girl in a post-apolyptic world where the sun was always covered by clouds, no plant life grew and the world was without color.
She was on some sort of journey to a temple and towards the end of the story she saw a plant grow in the barren earth, seeing color for the first time.
Anyone remember the title of this book or have any idea?
