This is another awesome book in the Percy Jackson series that I think is amazing! I like how The Sea of Monsters had lots of funny moments to keep readers interested and has so may suspenseful moments on another one of Percy's quests!
What could be worse than having Lastrigonian giants invading your school and throwing steaming hot balls and figuring out that Camp Half-Blood is in danger? In The Sea of Monsters, Percy finds out a secret which could change his thoughts about Posideon being his father, that Camp Half-Blood's protective tree, (which is Thalia, who got turned into a pine tree) on Half-blood hill is poisoned, and so the whole camp is in danger! And since it has been poisoned, people think that Chiron might have done this, so a new activities director comes to Camp Half-Blood. When Clarisse gets sent on a quest to the Sea of Monsters to get the Golden Fleece and bring it safely back to Camp, Percy, Annabeth and their allies want to help out, so they start a journey into the Sea of Monsters! And Percy's satyr friend Grover is trapped in the cave of the cyclops who is guarding the golden fleece- so they have to save him as well! This second installment into the Percy Jackson series is amazing, but I also wish it had a better plotline, but other then that, I think this book is awesome! (The Titan's Curse is my favorite though!) I recommend reading this!

Thanks for reading this comment and enjoy the book! :)

Another great book in the Percy Jackson and the Olympians series! This book is just as funny as the first book but has enough action to keep any reader hooked. As Percy, Annabeth and Tyson leave for another quest, it is nearly impossible to put this book down! Riordan successfully created a sequel that I think could be even better than the first! With the jaw-dropping cliffhanger at the end, I would encourage anyone searching for a compelling story (or anyone that is obsessed with the Greek gods,) to start reading this series!

This book is not Riordans best, but I like it. Oh yeah, I was looking through the comments, and I saw somebody call Annabeth ANNABELLE!!! You need to get your facts right and read more of Riordans books!!!!

I find this book super awesome, with all the monsters, but there might have been a little bit to much fighting.

This is a excellent book for 7+ to 10 after that this book is less challenging. It might be time for the kids who are over 10 to move on. This book is about demigods (half human half god) adventure story. And Greek gods and goddesses.(Greek Mythology on New York days, take place in about 2000 to 2009)

This book is amazing!!! The Gods and Goddesses are all in the "Western Civilization" as they call it and all the adventures they have really gets you fired up. This book is amazing and so are all Rick Riordon's others. This is a MUST read. Rick Riordon you are an amazing author, and your books are so interesting. Keep writing.

"The real story of the Fleece: there were these two children of Zeus, Cadmus and Europa, okay? They were about to get offered up as human sacrifices, when they prayed to save them. So Zeus sent this magical flying ram with golden wool, which picked them up in Greece and carried them all the way to Colchis in Asia Minor. Well, actually it carried Cadmus. Europa fell off and died along the way, but that's not important."

On Percy's last day of school, he and his friend/cyclops half-brother Tyson are attacked by giants. Annabeth appears and saves them before leaving for camp. When they arrive, Percy learns that Thalia's tree, the tree protecting the camp, has been poisoned and Chiron has been accused of poisoning and he was fired. If Thalia's tree fully dies, then the camp boarders won't be protected and more Monsters will start attacking the camp. This will continue unless they find another way to protect the camp borders or the camp will be overrun by monsters. To save the tree, a quest is given to find the Golden Fleece. Clarisse La Rue, a daughter of Ares, will lead the quest to find the Golden Fleece. Percy, Annabeth, and Tyson sneak off, not just for the Golden Fleece, but to find their friend Grover Underwood. They meet Luke on the ship, but are able to escape. They soon join with Clarisse on her quest. Her ship is destroyed passing through the Sea of Monsters and Annabeth and Percy continue their search for Grover after becoming separated from the others. After encountering the sirens and Circe, Annabeth and Percy reach the Polyphemus' cave. They are able to rescue Grover and Clarisse and Tyson helps defeats Polyphemus. They recover the fleece and head to Miami. Clarisse heads to camp and the others are captured by Luke. They are about to be killed before Chiron and the Party Ponies (other centaurs) rescue them and take them to camp. The Fleece is able to save the tree, but it also revives Thalia, whose spirit was in the tree.
