Angels' Blood (Standard format, CD, Library ed)

Vampire hunter Elena Deveraux knows she is the best--but she does not know if even she is good enough for this job. Hired by the dangerously beautiful archangel Raphael, a being so lethal that no mortal wants his attention, Elena knows failure is not an option--even if the task is impossible.
Because this time, it's not a wayward vamp she has to track. It's an archangel gone bad.
The job will put Elena in the midst of a killing spree like no other--and pull her to the razor's edge of passion. Even if the hunt does not destroy her, succumbing to Raphael's seductive touch just might. For when archangels play, mortals break.
