Lucifer is trying to kickstart the Apocalypse, but Jacob and his allies aren’t about to let that happen. But when a prophecy is revealed, thwarting the Prince of Darkness involves a field trip to the last place Jake expected. Vatican City.

Jake and his band of sexy, newly minted Demon Lords are closing in on the Unholy Duo of Gressil and Beelzebub. But first, they have to take care of the assassin society that keeps trying to take Jake out and deal with Abaddon, the crazed King of the Seventh Circle, and Todd must prove his skills in a joke off against his bizarre doppelganger.

Jake and his friends have finally taken down Beezlebub, and now six of the nine Circles of Hell are under their control. So, it’s time for a little vacation. Complete with beaches and all the hot succubi in sexy swimsuits! Unfortunately, Jake’s down time is interrupted by a mild inconvenience: the Apocalypse.

Jake has finally succeeded in destroying two prongs of the Unholy Trio. Now, all that’s left is public enemy number one: Beelzebub. The Lord of Flies won’t concede the Eighth Circle without a fight, though, so Jake has to find a way to power up, and fast. The answer? Hellfire. More specifically, the black Hellfire of fear. But to learn about black Hellfire, Jacob will have to venture into the Shadow World. 

Jacob and his allies have drawn the attention of the elusive BPI, or Bureau of Paranormal Investigations. Fortunately, the BPI has bigger fish to fry since Lucifer is trying to kickstart the end of the world. So, Jake will have to partner up with a beautiful BPI agent, a dark and sexy Shadow Queen, his loyal succubi, and the Toddster to stop the Apocalypse.

Gryff is finally returning to Mistral. But home is not the same as he left it, and neither is he. Now, Gryff has to figure out how to reintegrate himself into his classes and the Academy, just in time for midterms. Oh, and he’s got a wedding to plan, too.

Mason has dealt his first major blow to the Master’s forces. Now, it’s time to siege his fortress and take out his army of minions once and for all. But the war is not all Mason has to deal with. His women have some special news for him, and Nulena has a secret that will rock Mason to his very core.

Jacob and his succubi have defeated Azazel, and now Jacob is the demon king of the Fourth Circle. But that doesn’t mean the war’s over yet. Now that he’s king, Jake has to figure out how to rule in hell, keep from being stabbed in the back by the other demon lords and kings, and somehow, stay under Lucifer’s radar.

Gryff has his hands pretty full in the south. Not only is Varleth still missing, but now Veopa has awakened in the country of Vay. Plus, his women have been emboldened by his hawk wife Freya, and now they all want to bear him children. It’s a hard job, but someone’s gotta do it, and Gryff is certainly not complaining.

The war has officially begun, and it’s time for Mason to make his first offensive strike. But first he’s gotta round up his allies, overcome centuries of racial prejudices, and make sure the elves, ogres, dwarves, and mages don’t kill each other before it’s time to move out. Good thing he’s got his deadly, terrifying women to keep things in check. 

It’s time for Jacob to destroy Azazel once and for all and rescue the last succubus sister from the demon lord’s clutches. But mortals aren’t allowed in Hell, so Jacob and his harem of beautiful succubi must find a way to break the rules, infiltrate the circles, and fight through the thousands of demons looking to devour them. Just another day in the life of the succubus lord.

Jacob and his merry band of beautiful succubi face a new threat when several demonic assassins come to kill them. The battles will be fierce, and nothing can prepare the gang for the identity of their new enemy.

The capital Umo Portana has fallen to the goddess Utuni. But Gryff isn’t about to let the rest of Utun fall to the serpent Archon. The only problem is, Utuni’s blood aura makes her legions more powerful with each monster that’s killed, so Gryff and his team realize they’re going to need a little help. Gryff expects maybe a few Utun men to join his cause. He definitely doesn’t anticipate raising his own army. But, with his own forces, Gryff could lay siege to the capital and usurp Utuni once and for all.

Yes, I killed all the supervillians housed in the Grayville Ultramax Prison. I’m sure some, like the Shadow Knight, would consider that to be crossing a line and an unforgivable act of an unrepentant mass murderer. I consider it another high-performance day on the job. If the Shadow Knight has a problem with it, he knows where to find me. I really hope he does have a problem.

Gryff has gained a new power and a new shape-shifting wife. But his impromptu vacation is over. When his Mistral friends find him again, they inform him that Varleth is still missing, and the Archon Veopa has awakened in the country of Vay. Now, it’s up to Gryff to search for his friend and hopefully bring peace to the shape-shifting territories.
