Andrea, Lexie and Sarah are ordinary teens until the day the world shut down. In this chilling Christian YA tale, the girls and their families must develop faith and grit to survive. But can they find the strength when society collapses and technology fails? PULSE takes readers into a heart-pounding future for America, while affirming the power of faith in the darkest of times.

Now that an EMP has sent the United States into a seeming Dark Age, society has fallen apart at the seams. Andrea, Lexie and Sarah must survive despite the loss of technology, electricity, and worse, the threats of marauders and lawless opportunists. The appearance of FEMA camps might be reassuring except that the military seem determined to force civilians to enter them. Is the US government also a threat? Those who've survived the first months since the PULSE are either nearing the end of their resources, their wits, or their endurance. Only the few with enough RESILIENCE in heart or mind can continue to live without succumbing to the lure of the government camps or other dangers. Andrea and her family have the Martins and a growing community of survivors to help them get by. Lexie longs for the day when she and Blake can get married and have a family. That is, if they live long enough. Sarah and Richard hope to reach Aunt Susan's in Indiana; but what must they become to get there alive? And what will they find when they do? Can the US recover from the loss of technology before everyone and everything is destroyed?

Each day is important when it may be your last When an EMP struck the U.S. and rendered all electronics instantly useless, Andrea, Lexie and Sarah's lives changed forever. Their struggle for survival revealed surprising hidden strengths—but also weaknesses. Now, banded with other survivors, they hope for a temporary haven. But with no rule of law, and surrounded by foreign invaders and fellow Americans gone rogue, no one is safe. Andrea is determined to marry Roper—but first he must return alive! Lexie wants to marry boyfriend Blake, the brilliant, handsome science-geek, but a terrible accident threatens her hopes. Sarah would rather hide than fight—if only peaceful resistance was enough! Pushed to survive, resistance and will power must give way to DEFIANCE. But do the girls and the other survivors have what it takes to defeat the enemies who want them dead?
