The end is often underwhelming in case of Rick's books and the same happens with this. But the book is packed with humour and that's something credible considering what the protagonist are up against. The book also provides closure to all the seven and others as well. To sum it up the series was the best one out there by Rick. Percy wasn't the protagonist but the character development was phenomenal. What does it mean by being human. As apollo explores that he comes across human virtues and somewhere down the line also reminds us what humans are and what they should be. Well overall the book is just another masterpiece which is sure to entertain and preach you.
