Hounded, Hexed, Hammered - The Iron Druid Chronicles Volume 1

I love books about immortals and this one is definitely a good one. The fact that he doesn't act as if his being a druid is this big secret that will indanger all of humanity of some shit like that, Like many other books with a ‘secret world' do. He was active in his community and had a social life which is also a change of pace. 

It was funny and went by incredibly fast. I thoroughly enjoyed myself.
