Deep Insanity THE LOST CHILD
Deep Insanity: THE LOST CHILD
A mysterious illness has put millions in comas. An underground realm has appeared at its origin: Antarctica. Strange creatures make up its population, and undiscovered natural resources make it a gold mine. Many humans enter in search of fortune, but Daniel Kai Shigure searches for something deeper—a cure. Gifted with immunity to the illness, he might be humanity’s last hope.
