Wings of Vengeance (Hidden Wings Series Book Five)

No one knows of Lucian's long-held secret - a recently transformed Nephilim daughter.
Unfortunately for the Gray house, Lilith believes Emma is the one responsible for killing her father, and her deep-rooted hatred has turned into an envious obsession.
Powerful, with wings as dark as night, revenge consumes Lilith's every thought, only to be fueled by Lucifer's lies. Her newly transformed gifts have raised the danger level. Her aim is to strip Emma from everyone she loves, and has Lucifer's Fallen warriors to aid in her task.
Receiving help from Midway, Emma reconnects with friends of old and new, and hopes it will be enough to keep them all alive.
