The embodiment of the world's evil has but a single fear: one homeless girl.
Twenty-two-year-old Liz Linden and her nineteen-year-old brother, Jacob, have lived in the storm drains that run under Las Vegas for almost one year. There are many others living in the makeshift camps. She does her best to make their concrete camp into a home until she can save enough money to get them out of the tunnels and into an apartment.
Of late, her wish to get out has become desperate, as she's come to realize something else is down there - the offspring of malice and hypocrisy. It lives, it grows, and if not stopped, it will fully exist. It is the total of mankind's evils - The Darkest Sum.
