Seventh-grader Percy Jackson has recently discovered that he is the son of Poseidon, making him half human and half god, and along with a demigod and a satyr friend, must save his beloved Camp Half-Blood from evil forces determined to destroy it.

When Percy Jackson, a seventh-grade demigod living in New York, learns from his friend Annabeth that someone has poisoned the magical borders that protect Camp Half-Blood, Percy and his friends must journey into the Sea of Monsters to save their camp.

"Will the Greek god Apollo, cast down to earth in the pathetic moral form of a teenager named Lester Papadopoulos, finally regain his place on Mount Olympus? Lester's demigod friends at Camp Jupiter just helped him survive attacks from bloodthirsty ghouls, an evil Roman king and his army of the undead, and the lethal emperors Caligula and Commodus. Now the former god and his demigod master Meg must follow a prophecy uncovered by Ella the harpy. Lester's final challenge will be at the Tower of Nero, back in New York. Will Meg have a last showdown with her father? Will this helpless form of Apollo have to face his arch nemesis, Python? Who will be on hand at Camp Half-Blood to assist? These questions and more will be answered"--Provided by publisher.

"The Greek and Roman demigods will have to cooperate in order to defeat the giants released by the Earth Mother, Gaea. Then they will have to sail together to the ancient land--Greece itself--to find the Doors of Death"--Provided by publisher.

Demigod Percy Jackson, still with no memory, and his new friends from Camp Jupiter, Hazel and Frank, go on a quest to free Death, but their bigger task is to unite the Greek and Roman camps so that the Prophecy of Seven can be fulfilled.

"Greek and Roman demigods from the Prophecy of Seven must work together to seal the Doors of Death--and help Percy and Annabeth escape the Underworld in the process"--Provided by publisher.
