It's just an ordinary day when Lilly Averill's world breaks all down. The sun won't shine and disappeared from the sky. Everywhere is fire, which makes all the houses to ash. Lilly's parents are nowhere to be found and her friends are no longer in school or at home. Where's everybody? Lilly thinks she's left all alone on Earth, until she meets another girl, Edlyn Woods, who's also alone. Together they try to find their parents and all the other people, while discovering what happened to the Earth.
