When I started the book, I was a little lost since it had been quite a while since I read the earlier book (I have a bad memory) and couldn't remember much of the secondary characters. Dreamless was a pretty awesome book but the pacing was a bit slow. All that was made up for in Goddess, where things started happening so much, that I was aching to jump to the end of the paragraph to see what happened next. I loved the new pairings in the book. Heaven knows Hector (my favorite character in the book, by the way) needed a love interest. And the way the Lucas-Helen-Orion love triangle was resolved? Good one! I was laughing when Lucas hit the side of Orion’s head (you know which incident I am talking about).
The most interesting aspect of the book, however, for me, was the flashbacks of Troy and Camelot that Helen had. It was so pivotal to the story and the co-relations to the characters made for an interesting bit. Each of the stories added to the main so seamlessly – Cassandra, Achilles, Lancelot, and Hector (although I would have loved more mention of Andromache). We finally find out what that damn prophecy has been all about – the Tyrant, the Lover, the Shield, the Warrior – I was fruitlessly guessing at who could be who. Hades, you were awesome. I loved how he helped Helen because he thought it was right. Of all the Olympians, he was the only one who didn't join the war and I really liked him for it.
In short, this book is a must-read. I would also advise to read the earlier two books once again to enjoy this one much more.
