Book Review: "Black City" by Christina Henry

Former Agent of death Madeline Black may have been stripped of her wings—but she hasn’t lost her purpose… 

When Maddy finally killed her father, Azazel, she thought his depraved experiment died with him. But now Chicago has been infested with vampires immune to the effects of the sun, and the bloodbath is worse than she could have ever imagined. While the Agency refuses to interfere with other supernatural courts, Maddy is determined to do everything within her power to save her city—wings or no wings. 

But when the leader of the vampires requests that she turn herself in or risk more deaths, Maddy becomes a target for the very people she’s trying to save. Left with no other choice, she turns to Lucifer, the one creature who has the power to help her. But her grandfather’s aid has always come at a price… - from Amazon.com

Book Five in this series continues the story line almost immediately following Book Four. Having now rejected the agency, and losing her wings, Maddie Black finds Chicago taken over by vampires that are able to withstand sunlight, due to an experiment from her father, Azazel, had been conducting. In trying to rid the city of the vampires, Maddie asks for help from Lucifer, and as always there are other motives in play. I don't want to give away too much detail and spoil it for everyone, but a I was surprised at a couple of the things that came about. Sometimes when a series gets this far along, it becomes somewhat predictable, yet this one has brought some unexpected developments. Looking forward to book six.
