Asking help from the enemy was the last thing Samantha ever planned on doing, but who knew she would find her fate irrevocably sealed in the hands of a notorious Vampire Lord? In a world where Humans and Vampires have chosen to co-exist, the sacred orb of GreenHollow in the Northern Empire goes missing on a rainy night, right after the death of their ruler who was murdered in cold blood. It brought upon them an endless drought that can only be reversed when the sacred orb is found, and returned to its rightful place in the Empire. Ivan Chevalier, the heir and most feared son of the murdered Vampire King, has only two motives in life - to find his Father's perpetrator and behead him, his second motive is hunting down the sacred orb and restoring GreenHollow to what it used to be during his Father's reign. But when both motives lead him to the hands of his enemy's daughter, he has to choose between getting rid of her, or using her to his advantage by turning her into his blood slave. Samantha Dufort, a simple girl from EmptyHollow, is on the run with her younger brother after witnessing her Father being brutally murdered by a Vampire Lord. On the way, she gets abducted by slave traders.

But will she succeed when no one has ever left the Palace walls? Well, she was going to be the first to escape from these walls and find her missing brother. Twisted and trapped in the webs of Vampire politics interrelating with humans, Samantha discovers the main reason for her existence, a reason that could lead to changing the course of Empty Hollow. What happens when the Vampire Lord isn't the only darkness she has to run away from?
