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 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. 

The end is finally here. The Master, the elven Elite of Nalnora, and the bastard head of House Orrel are all that stand between Mason Flynt and a life of rich and kinky retirement. So, it’s time for the ultimate Flynt Family Massacre. 

Evan’s royal campaign to win over the people of Rahma has taken him to the northern peninsula. And straight to the gates of the underwater city of Pullis. The Green Glass Sect is up to no good under the sea, and it’s up to Evan and his party to save the merfolk from traitors and the ever-corrupting presence of miasma.

Evan and his party continue on to the peninsula of Rahma, but an ultimatum from the king hangs over Evan’s head. If he can’t get the Lord of Atheson to swear fealty to the crown, then he has been tasked with breaking the peninsula off the continent and letting it sink to the bottom of the ocean. 

Jacob now has seven newly minted Demon Lords, but his plate is still plenty full. The Unholy Trio of Baphomet, Gressil, and Beelzebub are still out to kill him, so Jake’s gotta stay one step ahead of the game. Good thing he has dozens of new succubi all vying to become his next Demon Lords. The question is which beautiful demon-woman will win "Who wants to be Jakey’s succubus?"

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. 

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.

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.

Ben is really coming into his title of Draco Rex. Not only has he discovered a new species of dragon, but now Jemma has bonded to the baby fire-breather named Tirian. And there are more dragons out there just waiting to be found. 

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 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. 

Mason’s plate is pretty damn full. The war with the Master is ramping up, but Mason and Aurora have been made heads of the Order of Elementa, their troops are being dispatched to every corner of the realm, Mason has made a metal dragon that kicks ass, breathes fire, and flies. And, oh yeah, all his women are raring to give him badass heirs. But when his tour across the land ends up conflicting with the Master’s plans, Mason finally stumbles upon the secret to defeating his nemesis.
