The World Shrank and I Grew

After every human suddenly shrinks to thumbnail size, the world turns into a perilous wilderness where survival is a constant battle. College student Mason Reid discovers a mysterious system inside him that allows him to grow stronger by consuming other creatures, absorbing their abilities. Alongside Evelyn Yates, a calm but formidable ally, they face mutated beasts, ruthless survivors, and a fanatical cult claiming the disaster is sacred. As they delve deeper, Mason and Evelyn uncover alien crystal cores scattered across the miniaturized world—possibly the key to restoring humanity's true size and reclaiming their shattered civilization.
