In a Nutshell:
Well, this one is hard to put in a nutshell. It is a sweeping epic story of the history of Dublin, Ireland. And when I say sweeping, he starts it from the very earliest Celtic community (complete with druid rituals and Celtic goddesses) and continues to the 16th century (with Christian conflict in a very Celtic believing country). He divides the histories per chapter and tries to have a generational thread throughout the chapters so there is a good flow for the whole book. He packs in some good fictional storytelling with believable characters in front of an historic backdrop of the complex development of Ireland's most infamous cities.
This was a great book, based on the history of Dublin, from the very beginning. You don't even know that he is teaching you history because the stories are so good. Do not be intimidated by it’s size, it is quite a page turner. You may want to buy tickets to Ireland after you are done. I think it is the first of a series. I cannot wait to buy the next one if that’s the case.
