I used to be your average, everyday girl but all that changed one night in Dublin when I saw my first Fae, and got dragged into a world of deadly immortals and ancient secrets …In her fight to stay alive, Mac Kayla must find the Sinsar Dubh – a million-year-old book of the blackest magic imaginable, which holds the key to power over the worlds of both the Fae and Man. Pursued by assassins, surrounded by mysterious figures she knows she can’t trust, Mac finds herself torn between two deadly and powerful men: V’lane, the immortal Fae Prince, and Jericho Barrons, a man as irresistible as he is dangerous.For centuries the shadowy realm of the Fae has coexisted with that of humans. Now the walls between the two are coming down, and Mac is the only thing that stands between them.
