Her grandmother told her that she suffers from hallucinations, but the truth is that Ivy has a wolf inside her that materialized when she was five years old. One day, she meets this stranger in a bar, who almost marked her as his Luna but then rejected her days after. Feeling humiliated, she wanders into the woods, only to have her life change forever. She then meets Alpha Blake of the Silver Moon Pack, who has been waiting twenty years to find his mate, only to discover her at the edge of death. To save her life, he must mark her as his mate immediately. When he learns that she knows nothing of the were-world, he must solve the mystery of why someone would go to such extremes to hide her with the help of his best friend and beta, Rick. But Rick has a secret that may end his decade-long friendship with Blake; he is the stranger who rejected Ivy, and he is her true mate. Alpha Blake also has a darkness in him that is not compatible with Ivy. The more he absorbs her power, the more he cannot contain it. Ivy also finds out the real reason to her parents' deaths, and she wishes she had never met the Silver moon pack.

My son is dying. That is the only truth that matters. Not that I am a half-blood with no pack standing. Not that my Crosser's Permit expired six months ago, and every night I fall asleep wondering if tonight is the night they come for us. Not that I mop floors and scrub blood off marble tiles in a hotel that belongs to the most dangerous wolf family in Silver Hollow, a city that does not officially exist, hidden inside Las Vegas like a knife inside a smile. My name is Tara De Leon. I was once a healer good enough to have been recruited by three different pack academies. Now I am invisible. A cleaning woman. A ghost in a uniform. I became invisible on purpose. Because invisible women survive. And survival is all I have left to give my son. Kai is seven years old. He has his father's jaw and my mother's eyes and a laugh that sounds like something the moon herself invented. He also has Fade Sickness, a supernatural disease that is slowly, quietly, methodically dissolving his wolf-soul from the inside out. Without the Blood Resonance Treatment, available only in Silver Hollow, available only to those with pack connections and pack money, he has maybe eight months. Maybe less. I would burn down every pack in this city to buy him one more day. I just never thought I would have to.

Malvina is facing frequent vampire attacks, but the hardest part is hiding who she really is from her colleagues and the police chief; Lacrimal city and Palaços are two distinct cities but both are suffering from cruel attacks by beings that until then were only in the popular imagination, but now live among us. And if we don't take a stand, accept them or kill them, they will live on after us.

For hundreds of years, witches have been a sub species to the vampire race, used as slaves to do the bidding of the undead creatures; but when one witch catches the eye of the vampire Prince, all that could change. The very way the world was run will be erupted into chaos, throwing off the balance that so many had died to protect. When Luna is ripped from her bed in the night, she knew her time had come, that she would pay for her father’s mistake; her world would crumble around her when her mother is killed by the prince and she is taken into his custody. A slave. But that is what all witches should expect, what they are born into. It is the way it had been for hundreds of years, Vampires were the hierarchy of the world, though not that the mortals knew that; and perhaps they never would. The undead creatures liked to feast on the unknowing, on those they could control, dis-guarding the corpses when they had finished. Luna is taken to A city one hundred and seventy feet under the streets of Paris, there she would have to learn how to be a good slave as those around her all believed that witches and warlocks deserved to be there, that they were a lesser species and needed to be controlled. But when the young witch reveals her power, all that was about to change. A mind link had never been formed between a witch and a vampire before, no one thought it possible, but when Luna makes it into Silas’ mind something happens; something that would change the course of their destiny and the fate of all those around them. With rebellion and chaos only around the corner, how will anyone survive?
