The Privilege of Sin (Drifter Series Book 4)

Kaitlynn Havens woke from a drug overdose to discover she could see an entirely new world--the Spiritual world--just as real and just as violent as her own. Yet, within that world, Kaitlynn was finding hope; hope that there could be more to her life than the dark alleys and nameless faces of a homeless street kid.
Then, just as suddenly as it had come, that newfound world is gone. Instantly, without warning, just gone, and Kaitlynn is devastated.
Suriyan, an Archangel, wishes for the girl to discover the faith within herself, not merely through her astounding vision. But Guile, the demon, has plans of his own; a plan to return Kaitlynn to a world of his own devising.An earthly world in which she's intimately familiar. A world she vowed never to return.
