The Sea of Monsters

The Sea of Monsters is the second book in the Percy Jackson series, written by Rick Riordan. It was published in 2006.

Meriwether College Prep
In Percy's dream, Grover was running from Polyphemus and went to a wedding shop. The shop then blew up. When Percy wakes up, he sees a dark object in the window which he described as a shadow belonging to no one and nothing. The next day at Meriwether College Prep, Percy is stuck playing dodgeball with Tyson, a friend, against large seventh graders who turn out to be Laistrygonians. They summon explosive cannonballs in an attempt to kill Percy but he is protected by Tyson who is unaffected physically or mentally by the monsters' cannonballs. Annabeth saves Percy by stabbing the last Laistrygonian, Joe Bob, from behind and takes Percy and Tyson back to Camp Half-Blood by calling the Gray Sisters and their gray taxi.

Returning to Camp
Upon returning, they find the camp under attack by two bronze Colchis bulls made by Hephaestus because Thalia's tree, which protects the camp, has been poisoned by an unknown intruder. (Percy and Annabeth discover that Luke is responsible.) Chiron was fired because he was suspected of poisoning the tree and is replaced by Tantalus, a spirit from the Fields of Punishment. Later, during the Chariot Races, they are attacked by Stymphalian Birds. Although Percy Annabeth and Tyson help stop the attack, Tantalus blames them, saying that they disturbed the birds with their "terrible driving".

The Quest Begins
Percy finds out that Tyson is a Cyclops and also a son Poseidon, making him Percy's half-brother. Annabeth and Percy ask Tantalus to send somebody on a quest after Percy tells Annabeth that Grover is in big trouble and can't get away from the Sea of Monsters to find the Golden Fleece, but he sends Clarisse, his favorite camper. Percy receives help from Poseidon, who gives them three Hippocampi. Hermes gives Percy three yellow duffel bags with vitamins and a thermos with wind in it. With Annabeth and Tyson, Percy travels on a passing cruise ship, the Princess Andromeda. Once they were on the ship it seemed empty. They fell asleep on the empty ship.

The Hydra
The Princess Andromeda is revealed to be owned by Luke and the maligned Titan Army. They are captured and learn that Luke is trying to help Kronos overthrow Olympus. They manage to escape the ship using Hermes' Thermos of winds. When reaching land, Percy sends Tyson away to find some doughnuts, as an excuse to talk to Annabeth about her past, alone. Percy is, however, surprised to find that Tyson actually found some doughnuts at a suspiciously nearby Monster Doughnut shop just 15 metres away. They then find that the shop is connected to the life force of the Hydra, which almost kills them. They are only just saved by Clarisse, who has a ship of her own, the CSS Birmingham, a confederate battleship that was given to her by her father Ares.

The Sea of Monsters
The CSS Birmingham is destroyed when the engine explodes while entering the Sea of Monsters (known to mortals as the Bermuda Triangle). Unfortunately, Tyson was inside, and neither him or Clarisse are seen by Percy or Annabeth after the explosion.

Circe's Island Percy and Annabeth are washed up at C.C.'s Spa and Resort (owned by the goddess Circe ), which is actually a prison for for male demigods and half bloods. Circe's 'helper' takes Annabeth, and gives her a makeover, while Circe turns Percy into a guinea pig. Using Hermes multi-vitamin tablets, Percy, as well as Blackbeard (also a prisoner of Circe) turn human. Percy and Annabeth escape on Blackbeard's ship while the pirates pillage and loot Circe's Island resort.

Polyphemus
Percy and Annabeth reach the island of Polyphemus and save Grover with the help of Tyson and Clarisse, recovering the Golden Fleece in the process. They make their way from Polyphemus's island and the Sea of Monsters to Miami, Florida, and Percy sends Clarisse, with the fleece, back to camp.

Tyson tells Percy that Polyphemus is fat and spoiled, that baby Cyclopes are left on the street to learn how to survive, learn to make things from scraps and to appreciates blessings instead of taking attention from the gods for granted.

Ending
Percy, Annabeth, Grover and Tyson are then captured yet again by Luke who tries to invite them to his hostibility onboard the Princess Andromeda. However, Percy manages to contact camp with an Iris-message, tricking Luke into admitting he poisoned Thalia's Tree. In a duel with Luke, Percy is nearly killed and gets his leg injured. He is saved by Chiron and his relatives, the Party Ponies. Chiron is rehired after being proven innocent, and the Golden Fleece cures Thalia's tree of Luke's elder snake poison from Tartarus in the Underworld. Then, Thalia, daughter of Zeus herself, is spewed out of the tree because the Golden Fleece does it's work too well bringing her back to life.

Prophecy
This book's prophecy is given to Clarisse.

"You shall sail the iron ship with warriors of bone,

You shall find what you seek and make it your own,

But despair for your life entombed within stone,

And fail without friends, to fly home alone."
