Mia Harper was not prepared for a solar flare to knock out the world's electricity. No one was, although Mia and her fifteen-month-old sister had a slight advantage: their father, a hardcore doomsday prepper, left them a safe haven to help them survive their new reality. Andrew Greene is Mia's childhood friend. On track to graduate college at nineteen years old, his sharp mind gives him an edge against the competition. How will the trio survive the harsh winters of Pennsylvania? How will they survive attacks from hungry wildlife? What will they do when faced with perhaps their greatest danger: the other survivors? Can they live in this new world? Or will their Shelter turn into their tomb?

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-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?

A year ago, a solar storm of unfathomable proportions wiped out the country's power grid. Most of the population died, leaving those left to pick up the pieces without the basics for survival. Now, with the country fighting to rebuild and survive, the defunct government is trying to seize control through any means, including the sacrifice of its military. As more people arrive to the small town near where Mia and Andrew live, chaos begins as they are forced to survive one of the worst winters in history. Mia and Andrew find themselves isolated from their friends, and from help. Faced with a corrupt government, the country's remaining survivors must come together, against fresh injustices and fight for the life they'd once enjoyed so easily. Will Mia's offer of peace be enough? Or will the country fall into chaos and destruction, destroying any hope of peace?
