I don't read a lot of urban fantasy--I'm just not into it that much, more an epic fantasy person here--but Kevin Hearne was on a panel I was moderating at Comic Con, so I decided to check him out, and I'm glad I did.

Hounded is the first book in his
Iron Druid Chronicles (which is now up to four books, going on five). The basic premise is that Atticus is an ancient druid, approximately 2100 years old but who looks 21, and a long time ago, he stole a magical sword from a Celtic god during a battle and he's been hounded (ha!) by the god ever since. In this book, he's hiding in Tempe, Arizona, where he can still connect to the earth, the source of his magical powers, and yet be relatively distant from the gods and the Fae who may be looking for him. But now he's been warned by the Morrigan that he's been found . . . and all sorts of creatures are after him.
I really enjoyed this book. I liked the character Atticus, I liked the set-up, I liked the druid magic mixed with the Fae and the gods and even the werewolves. It wasn't oppressively dark in atmosphere and tone, as a majority of urban fantasies are, and while there was certain lots of blood and battles, it was balanced with a tongue-in-cheek attitude. Atticus comes across as pratical and realistic and yet still enjoys life. His sidekicks--a wolfhound that he can literally speak to, an elderly Irish woman down the street, and his lawyers--are great characters themselves.
My only real complaint, easy to overlook while your enjoying the novel, is that Atticus' voice doesn't ring true with being 2100 years old. It really sounds more like he's 21, so that aspect of his supposed history is a little hard to swallow. Yes, he points out that he spends a lot of time learning the new vernacular and idioms and keeping up on current culture, and he does slip once in a while in minor ways, but this is written in the first person and at no point did I really feel like he was 2100 years old acting like 21. He felt like 21 all the way through.
But like I said, that's easy to ignore because the rest of the book is so good. So, I definitely recommend that anyone who enjoys urban fantasies . . . and even those who don't . . . check out
Hounded by Kevin Hearne. I've already got all of the sequels.
