The Mercy Thompson Series by Patricia Briggs.

The Mercy Thompson books are an urban fantasy series set in Washington State, specifically in the Tri Cities area of Washington state. Since this series is five books long and growing, I'm not going to do a series of entries dedicated to each book. I'll hit on some minor plot points here and described the characters.
It was a little weird for me to start reading this... I'm usually not a fan of "This Kind" of book. I don't read Laurell K. Hamilton (though I have in the past) and I haven't even finished the Sookie Stackhouse books of TrueBlood fame. I don't like chick lit or supernatural romance or lots of gore and sex. I actually rarely read anything that describes much sex at all, if you're gonna be picky. But this series is different. I can relate to the characters more and I really like the way the first couple are written. I've had issues with the second to last book, Bone Crossed, because it struck me as a the most chick lit-y of the series, but Silver Borne made up for it, in my eyes. This series isn't about showing off how well-versed in literature I am or anything but just enjoying a well-crafted storyline and characters you can really get care about, as much as you can for fictional characters. And for me... that's a lot. The names of the books in order are:
Moon Called
Blood Bound
Iron Kissed
Bone Crossed
Silver Borne

Mercedes Thompson, known as Mercy, went to college to study history and literature. Natrually, she's now a Volkswagon mechanic with her own shop. She's sarcastic, kind, fair, logical, open-minded, snarky, poised, responsible and a score of other adjectives that sound like lip service when you make a list like this. She's also a Native American shapeshifter, meaning she can turn into a coyote at will. This kind of shapeshifter is known as a Walker, and differs from werewolves in several important ways: her transformation is painless, voluntary and is not affected by the moon's cycle. She's also presumably not sterile, which is how she catches the eye of Samuel, one of the sons of  Bran, the leader of the North American werewolves. Mercy was raised by werewolves when her mother, who gave birth at the age of sixteen, came home to find a coyote pup in her daughter's crib. Bran agreed to take in her and raise her, giving her protection under the name of The Marrok, which is his title as leader. It's taken from the name of one of King Arthur's knights who was apparently a werewolf. As of the first novel, the werewolves have not yet come forward and revealed their existence although it isn't too far into the series before they feel the need to take that step, as the Fae did before them.

You see, in Mercy's world, the supernatural is fairly commonplace, even if it's not widely accepted. The Fae population of the world came out of hiding sometime in the not-so-distant past, a decision made by the Gray Lords (a sort of Fae ruling class). The term fae is a broad one used to describe a variety of pleasant and unpleasant supernatural creatures of myth, legend and fairy tale that are European in origin--everything from selkies, brownies and actual fairies to ogres, child-eating monsters and  other uncomfortably powerful creatures. It was deemed that the Time of Hiding was at an end when it appeared that the science of DNA and forensics threatened to reveal the supernatural creatures in hiding, whether they wanted to be revealed or not. Mercy actually purchased her garage from Ziebold Adelbertsmiter, known as Zee, a kind of fae known as a metalzauber or metalsmith because he knew that it would be impossible to continue running it once he was revealed to be fae. He's also fairly famous in the myth sense and one of the few fae that can stand iron.
 Most of the fae were driven from Europe by a combination of newly forged iron and in the wake of Christianity. They moved to the new world to escape, slaughtered a whole host of indigenous supernatural creatures on this continent and then iron and Christianity followed them over here anyway.

Since purchasing the garage, Mercy fixes a number of cars free of charge for the local vampire seethe, as she can't afford to pay them the protection fees they usually receive. It's sort of like paying the mob, because what they protect you from is mostly themselves; incidently, the vampires also haven't come out of hiding... there's really no way to put a positive spin on the fact that they drink human blood. Her contact within in the seethe is Stefan, a very pleasant, honorable, chivalrious vampire who almost painted his van black because of Buffy the Vampire Slayer. He ended up painting it to match The Mystery Machine because "even the Slayer is no match for Scooby-Doo." He reports directly to the Mistress of the Seethe, Marsilia, who has it in for Mercy for a variety of reasons. (SPOILER ALERT: the vampires are a big part of the reason Mercy is one of or possibly the only remaining Walker left in the United States.)

At the start of the story, Mercy was living a quiet unassuming life, mostly free of interaction with werewolves and any fae or creature who would cause her trouble until a very young werewolf named Mac showed up, ignorant of how to live as a wolf, half starved with a sad story that helped reveal a lot of corruption across the United States. Pack law is naturally brutal and not something to be ignored, so Mercy took it upon herself to help Mac, as her closest neighbor is the local pack Alpha, Adam Hauptman. After Mac is murdered and left dead on her porch, Mercy ends up reconnecting with Bran, Samuel and forming closer bonds with Warren, the only gay werewolf in Adam's pack, his boyfriend Kyle and Jessie, Adam's daughter. Meaning only to help Mac, Mercy ends up becoming more and more involved in the magic, rules and dangers of the world of the Fae, wolves and vampires. As of the fifth book, it's pretty much fair game as to who wants her dead the most.  She's killed or caused the death of both wolves and vampires, been raped, kidnapped, learned too much about the Fae, and eventually even becomes part of the werewolf pack. Like the coyote with the trickster spirit and too much bravado for such a little body, Mercy just can't seem to stay out of trouble.

Like I said, especially during Bone Crossed, the romantic aspect of this got to be a little too much for me. I like the actiony parts of the story much more than I like any of the parts concerning her attraction to Adam. It doesn't ever get explicit or explore the boundaries of sexuality or really even get beyond just general quasi romantic and intensity. It's never overtly Anita Blake-esque. I just don't really much care for mush or sex in my science fiction. It also is awesome but sucky at the same time that Patricia Briggs has gained such notoriety. This guarantees more books, but also means her books now come out in hardcover first, which equals 'spensive. I also fear the possiblity of a Mercy Thompson movie... which would be absolutely awful unless handled perfectly. Yeah. Like THAT happens.
