I have to say I would rate this book as 3.5 but there is no half so I went towards 4 only for the purpose that the story line got really interesting in the end. I am intrigue more with the story behind it all.

I have to say that a lot of the part where predictable. But I will just have to wait and see what will happen next and how it will turn out towards the end.

I am planning on reading the rest of the series.

I do like the character of Percy. I just don't like that they don't want to tell him all the details.
