Aaru is at war. The rebel angels are calling for Sam's exclusion from the Ruling Council and her banishment to Hel. But Sam's isn't the only future at risk. If they're defeated, Gregory and his brothers will face exile, losing everything they've spent billions of years to build.

The ancient demons of Hel have awakened, and one of them is gathering forces for an invasion of Aaru - which is pretty hilarious as far as Sam is concerned. Few know that Aaru is locked down tight after she banished all the angels. Nobody can get in. Nobody. Well, maybe nobody. The one being in Hel that might be able to restore Aaru is the archangels' prodigal brother. But he's presumed dead, having not been seen in over two million years. The remote possibility of an attack on Aaru isn't Sam's only problem. 

Seven Grigori enforcers have been murdered, lured to their death by a demon, and bearing the faint energy signature of a Fallen archangel no one has seen in over two million years. As the Iblis, it's Sam's responsibility to find the Ancient responsible and bring him to justice, but how can she manage that when she can't even keep her adopted infant angel from repeatedly killing his corporeal form?

Samantha Martin may be the leader of Hel, but she is also an imp in debt to a sorcerer. Luckily, he's vowed to wipe away all the favors she owes for one job - retrieve a stolen gem. But Gregory also needs her help. Interdimensional rifts are opening, spilling supernatural creatures into the world of the humans. Locating and closing the gateways takes a team of two - an angel and a demon.

Samantha Martin didn't want the title of Iblis and all the hellish responsibility that comes with it. She sure as heck didn't want these feathery angel wings permanently affixed to her back, although those have their perks. She especially doesn't want all the extra projects the ruling council keeps dumping on her plate.

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.

Samantha Martin is an imp, enjoying an extended vacation from Hel. All she wants to do is drink beer by the pool, play mischievous pranks on the humans, and get her hot neighbor in the sack. It's a relaxing break from her infernal home as long as she manages to avoid the angels, who won't hesitate to execute her on sight. But when her naughty hellhound lands her in trouble with the local werewolf pack, Sam is blackmailed into helping track and catch a killer. The steps she must take to appease the werewolves will put her right in the crosshairs of the angels.

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 jumps at the chance. 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.

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.

The newly fallen angels have quickly adapted and are using their abilities to advantage in their new world. The humans are not happy. The archangels are not happy. The imp is not happy. Sam has not only found herself ruling Hel but also responsible for the demon controlled section of North America, elven labor relations, and Amber’s bachelorette party. The bachelorette party thing is kinda cool, but the bridesmaid dress she’s got to wear isn’t, and neither is the fact that Gabe is going to be the one accompanying her down the aisle.

When I arrived at my uncle's house, I expected my relatives to be like me - outcast sorcerers who don't practice magic. I was right about the sorcery, but wrong about everything else. Rule two: Don't listen to the demon. My uncle chose a far deadlier power. He calls creatures of darkness into our world, binds them into service contracts, and sells them to the highest bidder. And I'm supposed to act like I don't know how illegal and dangerous it is. Rule three: Don't talk to the demon. All I had to do was keep my nose out of it.

Two sex demons could set Maui aflame with desire, but there's another creature with a more lethal inferno planned. Defeating it and saving the island will take all of Amber's newfound powers, as well as the help of friends new and old - especially since there's more to this enemy than what first meets the eye.

Amber has made a deal with the devil. To protect her incubus boyfriend, Irix, from the angels, Amber has agreed to journey to Hel and assist the humans there with their failing agricultural program. It's a project the botany major and half elf/half succubus would normally love, but the elves are sticklers for genetic purity and consider her an abomination.

Amber's summer internship is dying on the vine. Dozens of different diseases and pests have suddenly infected the California winery's grapes in a biblical-scale blight. The warmonger she thought was a one-night stand has shown up uninvited with an indecent proposal. And now she finds she'll be working side by side with an elf - a horticultural "expert" brought in to heal the plague-ridden vines, who would just as soon kill her as pass her the pruning shears. 

Raphael is an Angel of Order, sort of. His affinity for chaos makes him the perfect choice to investigate the trespass in Alaska of supernatural creatures not seen in eons. But the locals in Juneau have been keeping a secret for thousands of years -the disgraceful offspring of an angel and a demon. Raphael should execute her on the spot, or at the very least throw her into Hel with the rest of her kind, but Raphael has never been one to follow the rules.
