This is book one of the Iron Druid Chronicles Series.
I liked this one though I feel that Atticus O'Sullivan aka Siodhachan O Suileabhain, his birth name, should have been able to "fit" into the 21year old culture better because he had many years to study it - com'on man! The redemption was his realistic attitude towards fighting and self preservation even-though Atticus blames it on paranoia - no, it's 21 centuries of experience period - I wouldn't expect anything less. The book is funny – Oberon, his Irish Wolfhound, made this story entertaining and the goddesses were awesome little beasts. His lawyers and neighbors... crazy funny material if the author develop them in future books. I thought the whole new age shop was a good job fit for Atticus because it is a perfect front for someone with magic and knowledge of herbs and all things mystic - who would judge a creepy customer in that store? There are no complicated plots here to figure out though and it was just a good fun read.
Atticus O’Sullivan, last of the Druids, lives peacefully in Arizona, running an occult bookshop and shape-shifting in his spare time to hunt with his Irish wolfhound. His neighbors and customers think that this handsome, tattooed Irish dude is about twenty-one years old—when in actuality, he’s twenty-one centuries old. Not to mention: He draws his power from the earth, possesses a sharp wit, and wields an even sharper magical sword known as Fragarach, the Answerer.
Unfortunately, a very angry Celtic god wants that sword, and he’s hounded Atticus for centuries. Now the determined deity has tracked him down, and Atticus will need all his power—plus the help of a seductive goddess of death, his vampire and werewolf team of attorneys, a sexy bartender possessed by a Hindu witch, and some good old-fashioned luck of the Irish—to kick some Celtic arse and deliver himself from evil.
