Ascension series (Books 1-6) by S.M. Reine [epub]

Sacrificed in Shadow:

Lincoln Marshall is a small-town deputy with a very big problem. Six members of his church have been found dead, killed by a rogue werewolf. He'll have to make a deal with the Devil to save victims that have gone missing -- maybe literally.

Elise Kavanagh, preternatural investigator and exorcist, is the expert when it comes to violent deaths at the jaws of evil. She's also the demon known as the Godslayer. Elise jumps at Lincoln's case, and it's not just because of his down-home charm. Someone's laid a trap for her in Northgate, and she wants to find out who.

She'll have to team up with Rylie Gresham, Alpha of the last surviving werewolf pack, to figure out who's trying to blame the murders on werewolves. Only together can they stop the killings -- and uncover the secrets buried in Northgate.

Oaths of Blood:

Werewolves are immune to every illness and can heal any wound. It should be impossible for one to become possessed by a demon. But that's exactly what Seth Wilder is facing: a werewolf gone insane from possession. He has no choice but to deliver her to the only exorcist in America, Elise Kavanagh, who also happens to be a powerful demon known as the Godslayer.

Elise is in hiding when Seth and Rylie Gresham, Alpha werewolf, arrive seeking her help. She agrees, but everything has its price. What they learn about the possessed werewolf changes everything--Hell and Earth, the pack, and the future of the entire world...

Ruled by Steel:

Only a demon can save the souls trapped in Hell.

Elise Kavanagh failed to prevent the Breaking, and now Hell is spilling onto Earth. Now she's delved deep into the City of Dis in an attempt to stop the infernal armies--but even the legendary Godslayer is unprepared to face Dis's fiercest demons, not to mention the responsibility of liberating the humans they've enslaved.

On Earth, rogue angel Nash Adamson is wing-deep in damage control after the Breaking, and his fellow angels don't want to get involved. War is approaching the werewolf sanctuary. If Heaven won't help them, he'll have to turn to Hell for salvation.

Everything hinges on who can control the Palace of Dis. Elise and her allies have no choice but to rule by steel...

Caged in Bone:

Abel Wilder, werewolf Alpha, has gone missing, leaving his mate and the pack in a panic. His captor magicked his scent out of the sanctuary so that his mate can't track him down. Only one witch can cast a spell that powerful. James Faulkner has finally crossed a line that Elise Kavanagh can't ignore. Elise is going to have to hunt James down before the werewolf pack loses its Alpha and Rylie loses her mate. And Elise will have to find a way to make sure that James never bothers the pack-or anyone else-ever again.

Lost in Prophecy:

Book 5, The Ascension Series

Elise Kavanagh is too busy liberating slaves in the City of Dis to worry about what’s happening on Earth. She hasn’t even noticed that more than three thousand people have gone missing—not until an anonymous client hires her organization, The Hunting Club, to rescue them. The man asking for help doesn’t seem to exist. But the trail of clues is too strange to ignore, and she finds herself caught in the investigation. Werewolf Alpha Rylie Gresham is absorbed in troubles of her own. The pack is disobeying her, and the cult camped out in Northgate seems to be the source of the problem. Her mate, Abel, has resolved to fix it one way or another—even if it means going over Rylie’s head. Through secrets, lies, and assassination attempts, Elise and Rylie find that they have a new enemy in common. And what it takes to prevail might mean shattering the universe...

Torn by Fury:

Elise Kavanagh is marching on New Eden, the city angels have built from the bones of human victims. She's hellbent on making them atone for their sins--no matter the cost. Rylie Gresham has realized that werewolves are the key to defeating angels. They're apex predators, designed to bring powerful, immortal beings to heel. She has no choice but to follow Elise into war against Heaven…especially since it's the only way to protect her family from complete annihilation. The angels are prepared to defend themselves. Their magic will tear the universe apart. And if they have their way, there will soon be no Earth left to save...
