This is book number 4 in the Fever (Dell) series.
MacKayla Lane lies naked on the cold stone floor of a church, at the mercy of the erotic Fae master she once swore to kill. Far from home, unable to control her sexual hungers, MacKayla is now fully under the Lord Master's spell.
He has stolen her past, but MacKayla will never allow her sister's murderer to take her future. Yet even the uniquely gifted sidhe-seer is no match for the Lord Master, who has unleashed an insatiable sexual craving that consumes Mac's every thought--and thrusts her into the seductive realm of two very dangerous men, both of whom she desires but dares not trust.
As the enigmatic Jericho Barrons and the sensual Fae prince V'lane vie for her body and soul, as she rallies the sidhe-seers to fight an impossible battle and the power of the Dark Book weaves its annihilating path through the city, Mac's greatest enemy delivers a final challenge....
