This is such a great series. It is the seventh book in The Iron Druid series, so beware spoilers of the first six. Atticus O’Sullivan is a druid who was born thousands of years ago. For a majority of that time, he was the only druid left. He has recently taken trained another druid (Granuaile) and recovered his archdruid from a place where he was frozen in time. In this book, you get first person perspectives from all three druids- and it works. Each one of them are strong enough to carry a book on their own. Kevin Hearne is such a smart writer, effortlessly balancing pop culture and history (and an extensive knowledge of cultural religion). I am going to give this book 4 stars.
