Ruined World — Grace Hamilton

Trust is the first casualty of war...Disaster has struck the McDonald family. Everything they've built since the fall of civilization has been destroyed by a devastating fire. They've lost their community, supplies, and even loved ones. The death of Mike and James hits hardest of all. The other survivors are scattered. There's nothing left.All that remains is the indomitable will to survive. Jodi is lucky enough to have several family members survive the fire as they take to the road to find their new home. In this harsh new world, other survivors are often the greatest threat and trust must be earned. But the dangers of traveling America after the EMP force their hand. The missionaries of Helios seem to have good intentions and offer the weary group safe refuge in their enclave. But Jodi's unease grows as they move farther from the burned village, and the missionaries reveal their zealous ideology. Soon, Jodi will discover just how far the missionaries will go to control their new guests. And by that time, it may be too late to escape ....
