Devouring Darkness - Chloe Neill

As the only vampire ever born, not made, and the daughter of two very powerful Chicago vampires, Elisa Sullivan always knew her life was going to be...unusual. But she always wanted to make her own way in the world, likely away from her famous family. Then supernatural politics-and perhaps a bit of destiny-intervened, and Elisa had to steady her nerves and sharpen her steel, to fight for the city of Chicago. Luckily, Connor Keene, son of the North American Pack Leader, is right by her side. Elisa and some of the paranormal Ombudsmen she works with agree to escort a troubled sorcerer to Chicago for training, but they inadvertently set in motion a scheme of long-awaited magical vengeance. The city may pay an arcane price it can''t afford, unless Elisa and her team rise to the challenge.
