I haven't decided if I'm doing a full review on this. But I do want to say a few things.
I love this series. It came full circle with The Last Olympian. I really will miss Percy being the narrator. I am definitely going to be reading Riordan's other series. I already have The Red Pyramid on my iPad. Can't wait to start it.
I just love myths-- especially Ancient Greek and Roman. I really enjoyed how the older and lesser known Gods had more prominence in this book. I actually thought I had figured the ending out several times-- but was surprised. And surprised again. But I loved the ending! This was my favorite book of the series (well I liked The lightning Thief equally too). Maybe I just feel that way though because I just read it and it's so awesome.
Ok I can't say much more because I don't wanna spoil anything!
