Engine What Runs the World | Quinn Buckland
In the year 4324, technology has all but failed mankind, leaving a large social and economic gap between the wealthy that live in the tower, and everyone one else surviving in levels below the surface of the earth. Private detective, Smoke Callahan, already escaped the lower levels, but a suspicious case involving an elite tower resident will take Smoke back into the troubled depths of his past, and will thrust him headlong into a collision with a secret that the very pit of the earth hides. Smoke is faced with the toughest choices no man should have to make in a race against evil that will use the secret to bring death and destruction to all of humanity.
