Staked: The Iron Druid Chronicles by Kevin Hearne

Iron Druid Atticus O'Sullivan, hero of Kevin Hearne's epic New York Times best-selling urban fantasy series, has a point to make - and then drive into a vampire's heart.

When a Druid has lived for 2,000 years like Atticus, he's bound to run afoul of a few vampires - make that legions of them. Even his former friend and legal counsel turned out to be a bloodsucking backstabber. Now the toothy troublemakers - led by power-mad pain-in-the-neck Theophilus - have become a huge problem requiring a solution. It's time to make a stand.

As always, Atticus wouldn't mind a little backup. But his allies have problems of their own. Ornery archdruid Owen Kennedy is having a wee bit of troll trouble: Turns out when you stiff a troll, it's not water under the bridge. Meanwhile, Granuaile is desperate to free herself of the Norse god Loki's mark and elude his powers of divination - a quest that will bring her face to face with several Slavic nightmares.

As Atticus globetrots to stop his nemesis, Theophilus, the journey leads to Rome. What better place to end an immortal than the Eternal City? But poetic justice won't come without a price: In order to defeat Theophilus, Atticus may have to lose an old friend.
