If there is one city that Scarlett Bernard hates, it's Las Vegas. But when the cardinal vampire of Los Angeles convinces her to go investigate a new vampire-themed stage show, Scarlett quickly finds herself shoulder-deep in sequins, slot machines, and Old World intrigue. The show's creators are vampire celebrities Arthur and Lucy Holmwood, who once inspired characters from the original Dracula. Now, however, they have no qualms about announcing their true status to the human world.

Scarlett Bernard is used to cleaning up messes. As a human who cancels out any magic around her, Scarlett's job is to keep the supernatural world hidden - at any cost. But on the eve of the Vampire Trials, a two-day tribunal that allows the otherworldly community to air their grievances, Scarlett receives a blood-soaked message from Molly, her estranged former roommate. Molly, a vampire, had been living with 12 human college students...and in one terrible night, she slaughtered them all.

When LA’s vampires, witches, and werewolves make a mess, they call Scarlett Bernard to clean it up. Her ability as a null erases all magical traces from anything — or anyone — that comes within ten feet of her, and keeps humans in the dark about the city’s paranormal activity. One night when she’s called to a grisly crime scene, Scarlett is spied by the all-too-human LAPD cop Jesse Cruz, who strikes up a deal with her: he’ll keep quiet about the supernatural underworld if she helps him crack the case. She agrees, but the city’s chief vampire, Dash, starts to suspect Scarlett is behind the murders and will reveal all she knows of his shadowy empire. Now it’ll take more than Scarlett’s unique abilities to clear her name, keep the underworld underground, and track down the real killer.

Actions have consequences—a lesson Scarlett Bernard is learning the hard way. As a “null,” Scarlett has always been able to negate the powers of the supernatural beings that surround her. But now her reckless decision to permanently change Eli from a werewolf to a human has left the Los Angeles werewolf pack in shambles, and upset the balance of power among the city’s supernatural factions. To make matters worse, Scarlett’s employers discover that a newly changed werewolf is running amok in the city. To catch the rogue werewolf, Scarlett will need help from both Eli and Detective Jesse Cruz of the LAPD…a situation that will force her to finally choose between them.

As a null, Scarlett Bernard possesses a rare ability to counteract the supernatural by instantly neutralizing spells and magical forces. For years she has used her gift to scrub crime scenes of any magical traces, helping the powerful paranormal communities of Los Angeles stay hidden. But after LAPD detective Jesse Cruz discovered Scarlett's secret, he made a bargain with her: solve a particularly grisly murder case, and he would stay silent about the city's unearthly underworld.

Something wicked is at work in Colorado's supernatural community. Vampires are being paralyzed or killed with poison...a weapon favored by witches. This offense threatens to break apart the already-fractured alliance between witches and the undead. The state's cardinal vampire, Maven, summons boundary witch Allison "Lex" Luther to stop the killing before it ignites a war. Lex has barely started investigating when she gets another surprise: the biological father she's never met arrives on her doorstep.

After her twin sister’s brutal murder, former US Army Sergeant Allison “Lex” Luther vowed to protect her niece, Charlie. So when two vampires try to kidnap the baby, it quickly turns into a fight to the death - Lex’s death, that is.

Fitting into the Old World isn't going very well for Boulder boundary witch Allison "Lex" Luther: she may have earned a place in a vampire's service, but now it seems as if every supernatural creature in town has found a reason to hate her. And when Lex and her partner are assigned to investigate the suspicious disappearance of two vampires during the night of the full moon, they find themselves with more questions than answers.

Months after her battles in Wyoming, Allison "Lex" Luther is still struggling with the aftereffects of the psychic attack she suffered - and with the new developments in her own magic. Then, Lex’s boss, the cardinal vampire of Colorado, passes along a strange request from her counterpart in Atlanta. Hundreds of Civil War spirits have abruptly vanished in Beau Calhoun’s territory, and he wants Lex to figure out why. In exchange, Beau can help her understand boundary magic, which runs in his family line as well.

Cleaning up crime scenes and juggling supernatural politics is hard enough, but now Scarlett must face changes to every part of her personal and professional lives. What happens when the world's most powerful null goes on parental leave? And what will the Old World have waiting for her when she comes back?

Nevada Baylor has a unique and secret skill - she knows when people are lying - and she's used that magic (along with plain hard work) to keep her colorful and close-knit family's detective agency afloat. But her new case pits her against the shadowy forces that almost destroyed the city of Houston once before, bringing Nevada back into contact with Connor "Mad" Rogan.

Nevada Baylor can't decide which is more frustrating - harnessing her truthseeker abilities or dealing with Connor "Mad" Rogan and their evolving relationship. Yes, the billionaire Prime is helping her navigate the complex magical world in which she's become a crucial player - and sometimes a pawn - but she also has to deal with his ex-fiancée, whose husband has disappeared and whose damsel-in-distress act is wearing very, very thin.

When Nava Katz half-drunkenly interrupts her twin brother's induction ceremony into a secret supernatural society, she doesn’t expect to accidentally torch his life-long dream and steal his destiny. Horrified she’s now expected to take his place, Nava is faced with the one thing she swore off forever: a purpose. The all-male squad isn’t cool with a woman in their ranks and assigns her to Rohan Mitra: former rock god and their most ruthless hunter. He may be the perfect bad boy fling with no strings attached, but what happens when he won’t let her run - not even from herself?

There are two things Charlie Bennett despises: bullies and vampires. Which in her experience, are really the same thing. After the battle with the Quorum, she's left with no other option. The vampires' rule must end. But when more shocking secrets are uncovered Charlie wonders if she'll be alive long enough to follow through with her plan.
