When last we left Atticus, Oberon, and Granuaile, two certain huntresses from the Greco-Roman pantheon were going to chase them to Briton. Which is pretty much where Hunted by Kevin Hearne starts.
And let me tell you, given that the run starts in Romania, it's a long trip by ground to Windsor Castle. Much of which is punctuated with occasional run ins with Diana and Artemis, the coven of witches from 4 books back, Loki, Hel.... It's almost old home week in this one.
We also get a few cameos of new antagonists, like the Life Leech who is more or less a psychic vampire; the Manticore out of Sumerian systems; and what's looking to be a conspiracy to bring about Ragnarok by interests with ties to Tir na nog. Oh yes. Mr. Hearne is settling in for the long run with this one, since the sirens of ancient Greece long ago prophesied the end of the world within a few months of the end of this book. Which gives him plenty of wiggle room to squeeze a few books out concerning the conspiracy, figuring out where and what Theosphlis the vampire is doing, what's going to happen with Ragnarok now that Thor's dead...
But, back in the current book, The Morrigan fights Artemis and Diana early on to give our trio room to start running. (I'm sure a few Celtic fans will be annoyed with the character. However, one of her big plot arcs concerns trying to break out of patterns and personalities instilled by years of belief.) So, they run, including occasional narration from Granuaile, particularly after a run in with a vampire in the Black Forest. By the time they reach Windsor Castle and hook up with Herne the Hunter, the books 3/4 done, leaving us a bit of time for a resolution of the hunt and, later, a confrontation with the Manticore.
Really, this entire book, even during the chase, seems to be more of a transition into a larger metaplot that will extend beyond the trilogy system Hearne had been writing in. Which generally would suggest he just got a longer contract. (The first 3 got released every six months, then a year wait, then another 6 months between releases. I'm guessing this pattern will either continue, or we'll get a book a year, probably hardcover, if it follows the patterns of Jim Butcher and Laurell K. Hamilton and Kim Harrison.)
Any rate, the series is quite good, even if his portraal of Loki doesn't seem to fit the mythos. (Even is Loki was released from having snake venom in his eyes, and has been hiding and healing, he's still a god of chaos and trickery. That he seems to only show up and destroy godhomes with fire or throw a fireball at druids really doesn't do the Eddas justice. On the other hand, Hearne's portrayal of Thor probably annoyed his fan club, although Thor's mythos in no way really reflects Marvel's portrayal.)
As and added bonus, there's a novella concerning some of the 22 missing years between Tricked and Trapped. It's pretty good.
