A severe, world-wide blackout has resulted in a post-Apocalyptic earth where people must learn to navigate without electricity. In fifteen years, the world has fallen into barely managed chaos, with wide swaths of the former U.S. and other countries divided into militia controlled areas. A young woman named Charlie sees her father die before her eyes and then sets out on a quest to recover her kidnapped brother Danny. She enlists the help of her uncle Miles, a talented but troubled man with a complicated past. She also discovers that both of her parents were somehow deeply involved in whatever went on prior to the blackout. Secret pendants with possible technology to reverse the blackout play a large role in unfolding events.
