Mia Harper's life now is radically different than the one she has known. She lives in a world with no power, no phones, and practically no human contact. She and her best friend, Andrew Greene, are raising her two-year-year old sister Jilly, on their own. Mia, Andrew, and Jilly have been living in the dark for ten months; ever since a Coronal Mass Ejection changed life as they knew it. They made the best of it, and have settled into a routine, until... A stranger appears out of nowhere as summer approaches, shattering their peace. How will these three survive a hostile government, old enemies, and learning to become a family- all while scraping together enough food to fend off starvation?
