Mackayla Lane's ordinary life underwent a complete makeover when she landed on Ireland's shores and was plunged into a dark, deadly realm unlike any she ever imagined. In her fight to stay alive, Mac must find the Sinsar Dubh—a million-year old book of the blackest magic imaginable that holds the key to power over both the worlds of Fae and Man. Pursued by Fae assassins, surrounded by mysterious figures she knows she cannot trust, Mac finds herself torn between two deadly and irresistible men: V'lane, the insatiable Fae, who can turn sensual arousal into an obsession for any woman; and the ever-inscrutable Jericho Barrons, a man as alluring as he is mysterious.

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...
