In Trio of Sorcery, Mercedes Lackey presents three exciting short urban fantasy novels, including the return of Diana Tregarde and the debut of a brand-new heroine for the twenty-first century.

In 1876, we were called to Savannah, Georgia to help with an infestation of demons. If we'd known what we, my wife Evangeline, and I, were walking into, we'd have run the other way. As it was, we shared tea with a vampire and stepped into a battle we did not understand until it was too late.

When Mouse’s dad asks her to clean out her dead grandmother's house, she says yes. After all, how bad could it be? Answer: pretty bad. Grandma was a hoarder, and her house is stuffed with useless rubbish. That would be horrific enough, but there’s more - Mouse stumbles across her step-grandfather’s journal, which at first seems to be filled with nonsensical rants...until Mouse encounters some of the terrifying things he described for herself.

In a world invaded by demons, it's up to Katie and her Killers to restore order while also evading enemies - and friends - who want her in the worst way.

When Jack’s car breaks down in the middle of a cross-country road trip, the mysterious house at the top of the hill is a beacon of hope. If he can borrow a phone to call for help, he’ll be on his way in no time. But someone - or something - has other plans. Soon, Jack finds himself trapped in a nightmare that defies logic, where a depraved killer on the loose is the least of his problems. Will Jack escape before it’s too late?

Drunk customers. Shoplifting raccoons. Otherworldly visitors. As night shift clerk at the 24-hour gas station at the edge of town, Jack has pretty much seen it all.

Twenty-three years ago, a young girl went missing. Two days later her body was found lodged beneath the footbridge over Boulder Creek. The murder shook the town but they soon found it was only the beginning. A serial killer hides among them - a serial killer who strikes twice, sometimes three times a year. Mason Cooper couldn’t wait to leave Gillette Park. At 18, she headed off to college and the bright lights of Los Angeles, thinking she'd never return home to the broken family and forgotten friendships she'd left behind.

Monster hunter and mechanic Mark Wojcik has his hands full protecting innocent monsters from horrible people and innocent people from horrible monsters. His corner of rural Pennsylvania used to be relatively quiet—except for the ghosts, trolls, gnomes, and snallygasters. Then the Mob wars between the vampires and werewolves spilled over from the big city, along with supernatural bounty hunters, necromancer narcos, a monster trafficking ring, paranormal bookies, warring secret government agencies, and wicked witches.

The world is infested with demons, vampires, and ghosts who clash with wizards on the fringes of society. Faced with these horrors, there's only one thing a small-time wizard can do: absolutely nothing. Doing something could get a man killed. Armed only with a modern view of magic, a snarky bloodthirsty apprentice, and no concept of the phrase "fair fight", Maker is far too weak to try and change the world. But then a new group of warlocks moves into the area with the goal of making his life more interesting....

Meet the the Immortal Doc Holliday. Over a hundred years ago, notorious gambler Doc Holliday chose immortality over death, not knowing the price, but damned if it hasn’t been fun. Partying, playing, killing; yes, eternal life has been good. But now, Doc must repay his debt by saving Sofia, the last descendant of the beautiful shaman who granted him immortality.

Jared craved an ordinary life. Clock in, do paperwork, clock out. He gave up magic, joined the Meta Marshal Service, and just wanted to be left alone. Until a routine prisoner transport went awry and blew up his entire existence. That was when he found Cassie down on her knees in the wreckage, asking him for help. And he knew in that instant: Magic just wouldn't leave him alone. Now he's on a hunt for an escaped convict and a powerful ancient artifact with the potential to ruin their world for good.

Matt has a terrible life. Seriously—it's awful. It is so bad that Dan the Demon is shocked when Matt turns down his infernal offer: 10 years of a blissful life in exchange for his soul. But Dan is a salesman behind on his quota and his demonic managers are running out of patience. He forges Matt's signature on the dotted line, stealing his soul and thrusting him into a supernatural world he never knew existed. Matt must learn to navigate the hidden society of demons, faeries, demigods, and worse.

Thea Mendel is living in her car because there's a ghost in her house. At a Halloween party, she meets someone who believes her, a boy with green eyes and ghosts of his own named Thomas. Someone wants to do worse to Thea than kill her, and in order to find out who they are and what they want, the two of them will have to deal with a clan of unusually helpful vampires, unexpected Shoggoths, and all the weird that Rhode Island can throw at them. And that's a lot of weird.

We are the Night Vigil. We keep the Vigil, looking for the ones who can still be saved, the ones who aren't too far gone. We're the misfits and the muck-ups, unwanted by Heaven or Hell, given one last chance to atone for all the mistakes and missed chances, the pain we've caused others and ourselves, the good things we were afraid to do, and the bad things we embraced with open arms.
