White Heart of Justice

Since Lucifer claimed victory at Armageddon, demons, angels, and humans have coexisted in uneasy harmony. Those with waning magic are trained to maintain peace and order. But hostilities are never far from erupting.After years of denying her abilities, Noon Onyx, the first woman in history to wield waning magic, has embraced her power. She's won the right to compete in the prestigious Laurel Crown Race-an event that will not only earn her the respect of her peers but also, if she wins, the right to control her future.                          However, Noon's task is nearly impossible: retrieve the White Heart of Justice, a mythical sword that disappeared hundreds of years ago.
The sword is rumored to be hidden in a dangerous region of Halja that she is unlikely to return from. But Noon's life isn't the only thing hanging in the balance. The sword holds an awesome power that, in the wrong hands, could reboot the apocalypse-and Noon is the only one who can prevent Armageddon from starting again.
