3.5
Well, I liked this book. Seriously.
But this book is just full of clichés. The trio, with the funny guy, the guy who is destined for something bigger and the smart girl.
AND THE MOST ANNOYING THING:

Spoiler

Everytime the gods try to contact their children, the conversation ends too quickly. This in turn means that the IMPORTANT part of the conversation isn't even said. So frustrating.

The story is really intense, I mean it's just really REALLY action-packed, which is typical for Rick Riordan, I liked it. And the introduction of the Roman gods is pretty cool as well.

OF COURSE I WILL READ THE OTHER BOOKS. I want to know how the story continues. And I'm veeery excited for the Roman camp!!!!!
