Junkyard Druid

2016

ASIN B01M08QTJ6 has been moved to the latest kindle edition, as per guidelines A cursed druid, blackmailed by a faery queen to find a missing magic rock. Let's just hope they don't hack the druid off... for everyone's sake. Name's Colin McCool. Folks call me the Junkyard Druid. I hate that name. Despite my last name, I'm not "cool" like the other hunters in town. I don't run an occult bookstore, I've never owned a Harley, and I didn't inherit a family fortune passed down through generations of hunters before me. And I kind of have this curse on me that's messed up my life. So, things have gone to hell since I was cursed. I live in a junkyard, my mentor Finn is a heroin addict, I've got the Cold Iron Circle breathing down my neck, and the local Fae Queen Maeve is blackmailing me into doing her dirty work. Now I'm in way over my head trying to retrieve Maeve's stolen magic rock, all while helping my friend Belladonna solve a series of murders that may or may not involve the local werewolves. And did I mention that my girlfriend is a ghost? If I can just get the Faery Queen's tathlum back, and help Belladonna solve the murders... Then I just might live long enough to finish my first year of college.

Graveyard Druid

2017

Colin McCool here, otherwise known as the Junkyard Druid. Not my favorite title, but since it’s my only title I guess I’m stuck with it. But hey, things are looking up. Sure, a powerful and sentient magical artifact may have taken up residence inside my skull, and I’m still burdened with a nasty curse cast by an ancient sorceress of the Tuatha Dé Danann… ...but I’m trying really hard to look on the bright side of things. Seeing as how I’ve been dragged back into the world of the fae, I figure I may as well be of use. And if I can make a little scratch while using my druidic talents for good and not evil, so much the better. Which is why I took this job working for Austin’s vampire coven, cleaning up a ghoul infestation at the city cemetery. It’s not their work and they don’t want the heat, so they hired me to take care of it before it gets out of hand. Easiest. Job. Ever. I’ll just whack a few ghouls, hide the bodies, and collect my fee. I mean, seriously—what could possibly go wrong?

Underground Druid

2017

Colin McCool is hellbent on bringing vengeance to the doorstep of the Fae. But to do so, he’ll have to complete an impossible task in exchange for his passage to the mystical realm of Underhill. Will he outwit the Fae and survive this deadly undertaking? Or, will he be trapped in Underhill… forever? I thought the job was done when we broke up the Fae’s child sex trafficking ring. We rescued the kids, killed the ringleaders, and everyone was supposed to live happily ever after. But as it turns out, that only happens in fairy tales. Because when you’re dealing with the Fae I know, there’s always another nightmare waiting in the wings. Now I’m traveling into the belly of the beast—straight into Underhill, the mystical realm of the Fae. And to pay for my passage to and from the Faery lands, I’ll have to do something no one has ever done before. I’m going to steal the source of magic that powers Underhill itself. All I have to do is get to Underhill, steal a few uber-powerful magical relics from some Celtic gods, rescue the remaining children the Fae abducted, and get us all home in one piece. Oh, and I also have to outsmart Maeve, Austin’s local faery queen… because I know she’s not helping me travel to Underhill out of the goodness of her heart. Piece of cake, right? Yeah, right. One thing’s for certain… if this mission is going to be my swan song, I intend to go down spell-slinging.

Druid Justice

2018

After Colin cuts off their connection to Underhill, the high fae lose their position of magical supremacy. Sensing a shift in the balance of power, an unknown faction begins a brutal assault on the fae. Incensed by the injustice of their actions, Colin embarks on a one-man quest to find the persons responsible... so he can mete out some Druid Justice. When I came back from Underhill, I was certain that my dealings with the fae were done. Sure, I knew they’d be after me—I mean, I had cut off their unlimited supply of magic, after all.I just didn’t think I’d have to help them anymore. But when fae started dropping like flies and the Red Cap Syndicate came begging for my help, I felt kind of obliged to lend a hand. Thing is, nobody would have attacked the fae in such a brazen manner before I betrayed their queen. So, I guess it’s my fault all the fae are being assassinated. Oops. Do I feel bad about the killings? Nah. The fae have been preying on humans for millennia, and I think it’s about time someone turned the tables on them. That being said, it’s still wrong—so it is my duty to put a stop to it. The only problem is, I’m not the same druid who went to Underhill and lived. My Hyde-side is getting out of control again, and if I get in a tight spot I can’t take the risk of letting him out to save my skin. So, I’ll have to solve this case and deal with the killers the old-fashioned way… with magic and guile, all while handing out a little Druid Justice.

When his ancient druid master falls critically ill, Colin goes on a plane-walking quest to find a cure. Can the journeyman druid rescue the god of healing in time to save his oldest friend? I thought that learning magic from a druid master was tough, but that was before I started taking lessons from an insane quasi-god. For six long months I’ve been suffering under Click’s tutelage, boning up on my magic skills so I can survive the wrath of several Celtic gods and find a cure for my druid mentor, Finnegas. It’s my fault that the old man is hanging on by a thread, and I’m determined to save his life. Between surviving Click’s batshit crazy magic lessons and being harassed by the huldufólk, I’ve been trying to track down the Celtic god of healing. Only Dian Cécht can heal my master—and, he’s the only god Click trusts to do the trick. Unfortunately, DC has been damned hard to find. And just when we finally got a solid lead, Loki’s brother showed up to throw a wrench in the gears. Okay, so I may have killed Loki’s nephew. It’s not like he didn’t have it coming. Bottom line? I might have to fight an army of fire and frost giants to save Finn’s life. It’s a good thing I brought my wading boots, ‘cause shit’s about to get deep…

I write urban fantasy, paranormal suspense, and dark fantasy novels. My first series, THEM, is a jaunt through a post-apocalyptic central Texas where the dead walk, and vampires, werewolves and other unsavory creatures roam the night. It has elements of the zompoc genre, dark fantasy, and military survival fiction. My goal with this series was to give readers the same excitement I get from reading books by Larry Correia, Jonathan Maberry, and J.L. Bourne. On the other hand, my Colin McCool series falls squarely between urban fantasy and paranormal suspense. Colin's world is full of magic, mystery, and folklore come to life. I wrote this series because I love reading books by authors like Patricia Briggs, Kevin Hearne, Jim Butcher, and Neil Gaiman. And, like most authors, I try to write stories that I would enjoy reading. I currently live in the Hill Country near Austin, Texas, which is where much of my fiction is set. Most days you can find me in a local coffee shop or in my office working on my next book, or in my garage pummeling inanimate objects.
