Jessa Slade - The Darkest Night

Marked Souls - 4.5 Wishing you a demonic Christmas...
Possessed by a divine entity, Cyril Fane fought rampant evil and the pain of more private losses with a fiery golden sword…until he was beaten and left for dead by a malevolent force. Now exiled from his angelic brethren, he reluctantly joins the Chicago league of talyan—immortal warriors possessed by repentant demons—as his only chance to reclaim his sword and his place in the holy sphericanum.
Bella McGreay, mysterious mistress of the Mortal Coil night club, has also danced around an uneasy affiliation with the talyan. She has secrets of her own to keep, and as the days shorten toward the winter solstice, shadows are deepening all around. Even as she barricades herself against the joys—and terrors—of the Christmas season, she’ll have to decide whether the shadows or her secrets are more dangerous.
Bella and Cyril have good reason to fear evil when an old enemy returns to torment them and the Chicago league. But only together will they find a way to the light after the darkest night.
