More like 4.25 stars, so I didn't round up to 4.5 stars.
This is such a fun series. I was glad that the author fast forwarded a bit so we could see some development between Atticus and his apprentice, Granuaile. She's finally ready to be bound to the earth so she can become a full druid, but of course everyone and their mother is after Atticus, so his plans get interrupted several times. He fights gods, goes to hell, dines with the fae...and it's all in a day's work.
Oh and something that I've been wanting to happen between Atticus and Granuaile finally happens so I was completely over the moon. I don't want to spoil it, so go read about it!!!
Of course, I love Oberon. That dog totally puts this series over the top for me. His one-liners are classic. Atticus and Granuaile have a sexual tension that I just love, and I really enjoy Hearne's interpretation of mythology.
So, while some people may be tired of "more of the same", I say stick with what works, because this series, just works!
