Series background & context
This is the big Colin McCool saga, the branch of MD Massey's Druidverse that starts with a burned-out young hunter hiding from magic and grows into a long, escalating urban fantasy adventure. Colin lives in Austin, works at his uncle's junkyard, and wants nothing to do with the supernatural world he left behind. That would be easier if the fae, vampires, werewolves, and gods would return the favor.
They do not.
The hook of the series is simple and sturdy. Colin is funny, stubborn, badly outnumbered, and never quite as safe as he pretends to be. His junkyard home matters because it is ringed with cold iron, one of the few things that keeps fae power at bay, so the place becomes both fortress and trap. From there, the books open up into a hidden Austin filled with a faery court, vampire covens, werewolf packs, human hunters, and old myth walking around in modern clothes.
Celtic mythology is the backbone, but the series is not written like homework. Massey uses lore as fuel for fast scenes, ugly choices, and very personal stakes. Colin is not a finished hero at the start. He is grieving, carrying old damage, and dealing with a curse that can turn him into something dangerous. Over time he grows from reluctant survivor to apprentice, then to a far more capable druid who still has a talent for getting in over his head.
That long character climb is a big part of the appeal. Early books like Junkyard Druid and Graveyard Druid lean into monster cases and faction politics, while later entries widen the frame to include Underhill, divine grudges, supernatural wars, and even apocalyptic futures. The supporting cast matters, too. Friends, rivals, mentors, love interests, and recurring enemies all keep pushing Colin forward, usually by making his life harder.
The tone stays readable even when the plot gets dark. There is horror here, and real danger, but also sarcasm, momentum, and the kind of found family energy that keeps a long series from feeling cold. If you like urban fantasy that mixes swords, spellwork, Texas attitude, and a hero who wins as much through nerve as power, this is what the Colin McCool Junkyard Druid books do well.
It is a long ride, on purpose. The world keeps expanding, the stakes keep rising, and Colin keeps finding new reasons he cannot walk away.
