This book is good. 3 stars because, I don't think Nico is stupid enough to think that it's Percy's fault that Bianca died. Nico knew that it's Bianca's decision, then why would he think that it's Percy's fault? That ruins the whole story. That's the only part which I don't like. Most of the stories are good. Rick is quite creative, to be honest. I like how Rick made Apollo a fun person, like he is the best god.
