Percy Jackson and The Sea of Monsters is the second book of the Percy Jackson and the Olympians series. In the second book, one school year has passed since the events of the first book (The Lightning Thief), and Percy has been suspiciously safe without any monster attacks. That thought does not last for very long. 

Everything starts going wrong when Percy has a dream about Groover in a wedding dress. In the dream, Grover is in a cave with a cyclops the same day he was supposed to come back to Camp Half-Blood.

In the second book, they introduce one new character to the series Tyson. An adorable, kind, homeless orphan, who despite being two meters tall, became the target of ridicule from his classmates due to his sensitive baby attitude. He and Percy became each other’s only friends during the school year. 

This book is the shortest in the saga, but the humor is still one of the strongest qualities in the book. The plot gets more developed and the threat of war becomes more real and serious than ever.

Percy is still the amazing character we know and love from the first book. Percy is no longer just discovering this new, amazing, and chaotic world. Here we have a more mature and conscious Percy with what is happening around him. Even though a lot of people are still telling him that the Gods are using him, he knows how serious the war situation actually is, and how important it will be if he participates or not. His sarcastic humor, kind heart, and bravery are what makes his character so likable and enjoyable to follow through his adventures. 

Annabeth is not left behind. We learn more about her time with Thalia and Luke, along with her fears, desires, thoughts, qualities, and feelings. Her friendship with Percy becomes closer, more adorable, and romantic than ever. With their different qualities and characteristics, they complement each other very well. Percy completely adores Annabeth even though he doesn’t realize yet that what he feels for her is more than a friendship. You can feel it by the way he talks about her. Annabeth doesn’t seem to show anything that indicates something more than a friendship other than in really small moments that are enough to make your heart pound and butterflies appear in your stomach. 

Unlike the first book, the action scenes in The Sea of Monsters are longer, and there are definitely more of them than in the first book. The writing is still amazing and so easy to imagine and follow along with, that it just made the action so much more entertaining to read. 

I would say that this book is a really good second part of the story. We know more about the plot and the future that it holds for Percy while deepening in the rest of the characters. The ending similarly to the first book ends with a plot twist that opens doors to many different directions in the plot. It will leave you wanting to read the third book the second you finish this one.
