Samantha Martin is an imp, bound by an angel who allows her to live among the humans . . . as long as she follows his rules.  It’s never easy for an imp to follow the rules, especially now that Sam’s brother, Dar, has found himself in hot water.  He needs her help to retrieve an artifact from the vampires, or the powerful demon he owes a favor to will enslave and torture him for centuries.  It should be a simple courier job, but with demons nothing is simple.  Sam reluctantly attempts to help her brother, trying not antagonize the vampires or the demon gunning for him, all while chafing to comply with the restrictions her angel has placed on her as a bound demon.

What do a dead cosplayer and a ritual murder have in common? Plenty. Solaria Ainsworth isn’t a paladin, she’s not even an ordained Templar Knight, but she can’t resist poking her nose into police business when magicians are found murdered in Baltimore. When the murders spread to include those of the magical group Haul Du, she rethinks her participation in the investigation. Why should she bother to assist a group that kicked her out the moment they discovered she was a Templar, the group that forbade any of their members to have contact with her? Is the killer an angel or a demon, or both? No matter her old grudge, Aria can’t ignore the bloodbath right under her nose, and she definitely can’t ignore the practice of death magic that has stolen innocent lives and souls.

For once no one wants to kill Samantha Martin.  She’s free to do all the things a mischievous imp loves to do- like remove all the county speed limit signs, and wrap City Hall in crime scene tape.  Her only worry beyond organizing the delivery of her boyfriend’s birthday present, is writing those pesky four nine five reports for the Ruling Council of Angels.  But imps can never stay out of trouble for long.Demon corpses have been found drained of all energy, their spirit selves ripped clean from their bodies.  Sam’s angel, Gregory, considers her a prime suspect, so when an angel is discovered dead in the same manner, he drags her to Seattle and Juneau to try to clear her name.  The race is on to find the murderer before Sam’s secret is exposed and she’s blamed for the deaths.  But is a devouring spirit really the killer, or is there more to the deaths than either Sam or Gregory suspect?
