Ten years ago, Grace saw a thing that would forever change the course of history. When bad in its purest form is unleashed over the world, she yet others from their spiritual community already are concealed deep in the hillsides of Tennessee, abiding by every guideline that will keep them safe, pure–and alive. So long as they stay there, behind the reddish perimeter. Her old brother’s questions as well as the arrival from the 1st outsiders she’s seen in 10 years set in motion events which will question everything Grace has generated her existence on. Enemies rise on all sides–but who is the real enemy? And what will it cost her to uncover the reality? For the first time, bestselling writers Ted Dekker and Rachelle Dekker team up and deliver a rigorous, tightly focused trip through one of the most treacherous world of all.
