*I let it go—all of it. Everything I’d been saving up all my life, building and growing inside me, too much to hold in one half-human body. It pushed and fought to be free with a force that turned me into a bomb with a timer vibrating on zero. I was free. But so was everything I’d fought so hard not to be…* Brothers Cal and Niko Leandros know trouble when they see it—and then proceed to wipe the floor with it. But now it seems their whole world is falling to pieces. Cal’s nightmarish monster side is growing ever stronger, changing Cal physically as well as mentally. Which is exactly what Grimm—Cal’s savage doppelgänger—wants. And when a covert supernatural organization decides that it’s time to put Cal down before he threatens pretty much everything else in existence, the brothers find themselves in a fight they actually might lose. But the dark temptations Cal has denied all his life may prove to be exactly what can save them. Even if he must fall forever…

Welcome to New York City - a troll under the Brooklyn Bridge, a boggle in Central Park, and a beautiful vampire in a penthouse on the Upper East Side. Most humans are oblivious to the preternatural nightlife around them, but Cal Leandros is only half human. His father’s dark lineage is the stuff of nightmares – and his entire otherworldly elf race are after Cal.

New from the national bestselling author of Deathwish It's time to lock, load, and hit the road...** Once, while half-human Cal Leandros and his brother Niko were working on a case, an ancient gypsy queen gave them a good old-fashioned backstabbing. Now, just as their P.I. business hits a slow patch, the old crone shows up with a job.

Picking up a small pink shoe from the grass forever changed young Jackson Lee’s life. Not only did its presence mean that his sister Tessa was dead—murdered and stuffed in the deep, black water of a narrow well—but the shoe itself told him so. Tessa’s death triggers an even more horrific family massacre that, combined with this new talent he neither wants nor can handle, throws Jack’s life into a tailspin. The years quickly take him from state homes to the streets to grifting in a seedy carnival, until he finally becomes the cynical All Seeing Eye, psychic-for-hire. At last, Jackson has left his troubled past behind him and found a semblance of peace. That is, until the government blackmails him. Helping the military contain the aftermath of a bizarre experiment gone violently wrong, everything Jackson knows about himself will change just as suddenly as it did with his little sister’s shoe. And while change is constant...It’s never for the better.

I looked at the metal coated with blood—so very much blood—the same color as the darkest crimson rose. I was undoing this. I was making this right. And I’d like to see the son of a bitch who thought he could stop me. Bar owner Trixa Iktomi knows that inhuman creatures of light and darkness roam Las Vegas-especially since she’s a bit more than human herself. She’s just been approached with an unusual proposition. Something has slaughtered almost one thousand demons in six months. And the killing isn’t going to stop unless Trixa and her friends step into the fight.

Stefan Korsak and his genetically-altered brother have evaded the Institute for three years. When they learn the new location of the secret lab, they plan to break in and save the remaining children there. But one of the little ones doesn't want to leave. She wants to kill...

I stopped and let them circle me, first because it was intriguing and, second, because, honestly, what could they do? Only knives, but all armed, and that made them even more interesting. Interesting. Fun. Playtime… Taking on bloodthirsty supernatural monsters is how Caliban and Niko Leandros make a living. But years ago—before they became a force to be reckoned with—the brothers were almost victims of a very human serial killer. Almost. Unfortunately for them, that particular depraved killer was working as apprentice to a creature far more malevolent—the legendary Spring-heeled Jack. He’s just hit town. He hasn’t forgotten what the Leandros brothers did to his murderous protégé. He hasn’t forgotten what they owe him. And now they are going to pay… and pay… and pay.…

When half-human Cal Leandros wakes up on a beach littered with the slaughtered remains if a variety of hideous creatures, he's not that concerned. In fact, he can't remember anything-including who he is. And that's just the way his deadly enemies like it...

After saving the world from his fiendish father's side of the family, Cal Leandros and his stalwart half-brother Niko have settled down with new digs and a new gig-bodyguard and detective work. And in New York City, where preternatural beings stalk the streets just like normal folk, business is good. Their latest case has them going undercover for the Kin-the werewolf Mafia. A low-level Kin boss thinks a rival is setting him up for a fall, and wants proof. The place to start is the back room of Moonshine-a gambling club for non-humans. Cal thinks it's a simple in-and-out job. But Cal is very, very wrong. Cal and Niko are being set up themselves-and the people behind it have a bite much worse than their bark...

*People die. Everyone knows that. I knew it intimately as everyone in my life died thanks to my one seemingly harmless mistake. I'd brought down Heaven, lifted up Hell, and set the world on fire, all due to one slip of the memory. I forgot the pizzas...* Caliban is a dead man. The Vigil, a group devoted to concealing the paranormal from humanity, has decided Cal has stepped out of the shadows once too often, and death is the only sentence. They plan to send a supernatural assassin into the past to take down the younger, less lethal Cal. But things change when The Vigil makes one last attempt on Caliban's life in the present—and end up destroying everyone and everything he cares about. Now, Cal has to save himself, warn those closest to him, and kill every Vigil bastard who stole his world. But if he fails, he and everyone in his life will be history…

Now you see it… Now you don’t… Now you’re history. There are demons in the world, Monsters. Creatures that would steal your soul. You might hide under your covers at night and pretend all’s right with the world, but you know. Even if you don’t want to admit it… Las Vegas bar owner Trixa Iktomi deals in information. And in a city where unholy creatures roam the neon night, information can mean life or death. Not that she has anything personal against demons. They can be sexy as hell, and they’re great for getting the latest gossip. But they also steal human souls and thrive on chaos. So occasionally Trixa and her friends have to teach them manners. When Trixa learns of a powerful artifact known as the Light of Life, she knows she’s hit the jackpot. Both sides-angel and demon-would give anything for it. But first she had to find it. And as Heaven and Hell ready for an apocalyptic throw-down, Trixa must decide where her true loyalty lies-and what she’s ready to fight for. Because in her world, if you line up on the wrong side, you pay with more than your life…
