A simple infection can spell death in a world without proper medical care, though unlikely allies are found in even the darkest corners of the world in book 4 of Echoes of the End. A new blend of metals was promised to be stronger and last longer than traditional steel ever could – until it started breaking down into hyper-combustible byproducts. Thousands of miles of pipelines go up in an instant, their chain reactions setting of fires that destroy cities, crumble buildings and reduce the civilized world to ash. As the survivors pick through the ruins of their world, one mother will stop at nothing to rescue her children – even if that means traversing the country to find them. Meanwhile, deep in the Everglades, protected from the destruction ravaging the world by his guilt and penance, one man will hold the salvation of a young girl in the palm of his hand. .
