In a world where "witches, vampires, werewolves, and shape-shifters live beside ordinary people" ( Booklist), it takes a very unusual woman to call it home. By day, Mercy Thompson is a car mechanic in Eastern Washington. By night, she explores her preternatural side. As a shape-shifter with some unusual talents, Mercy's found herself maintaining a tenuous harmony between the human and the not-so- human on more than one occasion. This time she may get more than she bargained for.

Mercy Thompson's life has undergone a seismic change. Becoming the mate of Adam Hauptman - the charismatic Alpha of the local werewolf pack - has made her a stepmother to his daughter, Jesse, a relationship that brings moments of blissful normalcy to Mercy's life. But on the edges of humanity, what passes for a minor mishap on an ordinary day can turn into so much more.... After an accident in bumper-to-bumper traffic, Mercy and Jesse can't reach Adam - or anyone else in the pack for that matter. They've all been abducted.....

Car mechanic Mercy Thompson has always known there was something different about her, and not just the way she can make a VW engine sit up and beg. Mercy is a shapeshifter, a talent she inherited from her long-gone father. She's never known any others of her kind. Until now.

Mechanic Mercy Thompson has friends in low places - and in dark ones. And now she owes one of them a favor. Since she can shape-shift at will, she agrees to act as some extra muscle when her vampire friend Stefan goes to deliver a message to another of his kind. But this new vampire is hardly ordinary - and neither is the demon inside of him.

An unexpected phone call heralds a new challenge for Mercy. Her mate Adam’s ex-wife is in trouble, on the run from a stalker. Adam isn’t the kind of man to turn away a person in need—and Mercy knows it. But with Christy holed up in Adam’s house, Mercy can’t shake the feeling that something about the situation isn’t right. Soon her suspicions are confirmed when she learns that Christy has the furthest thing from good intentions. She wants Adam back, and she’s willing to do whatever it takes to get him, including turning Adam’s pack against Mercy.

Mercy Thompson's life is not exactly normal. Her next-door neighbor is a werewolf. Her former boss is a gremlin. And she's fixing a VW bus for a vampire. But then, Mercy isn't exactly normal herself.

Attacked and abducted in her home territory, Mercy finds herself in the clutches of the most powerful vampire in the world, taken as a weapon to use against alpha werewolf Adam and the ruler of the Tri-Cities vampires. In coyote form Mercy escapes - only to find herself without money, without clothing, and alone in the heart of Europe. Unable to contact Adam and the rest of the pack, Mercy has allies to find and enemies to fight, and she needs to figure out which is which.

My name is Mercedes Athena Thompson Hauptman, and I am a car mechanic. And a coyote shape-shifter. And the mate of the Alpha of the Columbia Basin werewolf pack. Even so, none of that would have gotten me into trouble if, a few months ago, I hadn’t stood upon a bridge and taken responsibility for the safety of the citizens who live in our territory. It seemed like the thing to do at the time. It should have only involved hunting down killer goblins, zombie goats, and an occasional troll. Instead, our home was viewed as neutral ground.

I am Mercedes Athena Thompson Hauptman. My only “superpowers” are that I turn into a 35 pound coyote and fix Volkswagens. But I have friends in odd places and a pack of werewolves at my back. It looks like I'm going to need them. Centuries ago, the fae dwelt in Underhill - until she locked her doors against them. They left behind their great castles and troves of magical artifacts. They abandoned their prisoners and their pets. Without the fae to mind them, those creatures who remained behind roamed freely through Underhill wreaking havoc. Now one of those prisoners has escaped.

Charles Cornick is the son of the leader of the North American werewolves - and his father's enforcer. Anna Latham, a rare Omega wolf with a calming presence, is his mate. They go where they are needed, handling problems in werewolf packs throughout the country. But this time the danger is closer to home, as an enemy armed with witchcraft threatens Charles and Anna's own pack.

For once, mated werewolves Charles and Anna are not traveling because of Charles' role as his father's enforcer. This time their trip to Arizona is purely personal, as Charles plans to buy Anna a horse for her birthday. Or at least it starts out that way....

Now that the werewolves have revealed themselves to humans, they can't afford any bad publicity. Infractions that could have been overlooked in the past must now be punished, and the strain of doing his father's dirty work is taking a toll on Charles. Nevertheless, Charles and Anna are sent to Boston when the FBI requests the pack's help on a local serial killer case. They quickly realize that not only the last two victims were werewolves - all of them were.

Mated to werewolf Charles Cornick, the son - and enforcer - of the leader of the North American werewolves, Anna Latham now knows how dangerous being a werewolf is, especially when a werewolf opposes Charles and his father is struck down. Charles's reputation makes him the prime suspect, and the penalty for the crime is execution. Now Anna and Charles must combine their talents to hunt down the real killer - or Charles will take the fall.

Car mechanic and sometime shape-shifter Mercy Thompson has learned, the hard way, why her race was almost exterminated. When European vampires immigrated to North America, they found Mercy's people had a hidden talent - for vampire slaying. Unfortunately for Mercy, the queen of the local vampire seethe has discovered her true identity. She's also furious when she learns Mercy has crossed her and killed one of her vampires. Mercy may be protected from direct reprisals by the werewolf pack (and her interesting relationship with its Alpha), but that just means Marsilia will come after Mercy some other way. So Mercy had better prepare to watch her back.

In the wilds of the Northern California mountains, all the inhabitants of a small town have gone missing. It's as if the people picked up and left their possessions behind. With a mystery on their hands and no jurisdiction on private property, the FBI dumps the whole problem in the lap of the land owner, Aspen Creek, Inc. - a.k.a. the business organization of the Marrok's pack. Somehow, the pack of the Wolf Who Rules is connected to a group of vanished people. Werewolves Charles Cornick and Anna Latham are tasked with investigating.
