Imp series by Debra Dunbar

Book 1 - A demon bound Think your landlord is a demon from hell? This one really is. Samantha Martin is an imp. She throws her gum on the floor of five star restaurants, bounces inflatable holiday decorations down the highway at rush hour, and clips jaywalking pedestrians with her car. Sam also likes to kill people and keep their souls inside her for all eternity, but acting on that particular urge will get her killed by the angels, who are determined to rid the world of her kind. Sam works hard to keep her human identity realistic: she owns slum rental properties, and she is trying to get her hot neighbor into the sack. When she kills a werewolf in an act of self-defense, his pack leaders blackmail her into helping track and kill a rouge angel. The very actions she must take to appease the werewolves put her at risk of being discovered and killed by the angels. Because angels show demons no mercy.

Book 2 Satan's Sword 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.

Book 3 - Elven blood Sam may be the Iblis, but she is also an imp with a price on her head. The powerful demon, Haagenti, won’t rest until she’s dragged back to Hel for “punishment”. Sam knows she can’t face Haagenti and win, so when an Elf Lord offers to eliminate the demon in return for her help, Sam accepts. It’s a simple job – find and retrieve a half-breed monster dead or alive. But finding this demon/elf hybrid isn’t proving easy and time is running out.

Book 4 - Devil's paw 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?

Book 5 - Imp forsaken Sam is banished to Hel, the bond with her angel, Gregory, broken. Six Elven kingdoms are battling for supremacy, and she’s broken and injured in the middle of the most hostile one. Shooting the top off a royal throne, committing fraud in the completion of a contract, and threatening a high lord hasn’t endeared her to the elves, either. If she wants to free the enslaved humans they hold, she’ll need to find a way to help unite their kingdoms.
But elves aren’t the only problem facing Sam. The ancient demon, Ahriman is holding her to the terms and conditions of the breeding contract she signed – and one thousand years under his claw is looking to be the most terrifying thing in all of Hel.

Novella - Imp (est to read before book 1 for background info) Demon young are cruel, especially to little imps like Az. No matter where she hides, even deep in the swamplands, her siblings eventually find her and hurt her, ripping off her scales and slicing her wings. Many demons don’t live to adulthood. Only the strong survive. And the clever.
Survival isn’t looking probable for Az, with eldest brother, Paquit, determined to rip her to shreds at every opportunity. When her other brother, Dar, proposes a trip through the angelic gates into the land of the humans, she jumps at the chance. Finally, a fun adventure safe from Paquit’s cruelty and attacks. Or maybe not.
