Trained to kill demons, she never thought she'd join their side. Seventeen-year-old Nova Fandera has always known her duty to bring honor to her family by becoming an Undivided-a demon hunter bonded to and given strength by an angel-but as desperate as she is to prove herself, she is kept trapped within the confines of her father's estate with no explanation as to why. When she hears of the coming blood moon-a rare night when demons feed off the moon's essence and become stronger-Nova recklessly escapes, determined to bring the head of a powerful demon to her father's doorstep. What she doesn't expect, however, is the aid of her enemy and a deal offered: answers to the questions her father won't even acknowledge in return for training six young half demons. But hunters don't make deals with devils. That is, unless they're left with no other choice. Nova soon discovers that the answers to her questions about her identity and family's history are more than she bargained for. A unique and powerful artifact that heeds her call, a mystical lotus tattoo, memories of other lives, and lost love... The mysteries keep piling up with no end in sight. When a faceless Darkness threatens her from chasing after these answers, Nova risks everything she's ever known and teams up with the very beings she was raised to hate. Yet the journey is only just beginning. A lifetime of lies and betrayals is unraveling with the red string of fate, leading Nova to a truth no one is prepared for. One that screams for retribution and cries for the lost. But Darkness will do anything to stop her-even if it means destroying the world.
