Percy, expelled from six schools for being unable to control his temper, learns the truth from his mother that his father is the Greek god Poseidon, and is sent to Camp Half Blood where he is befriended by a satyr and the demigod daughter of Athena who join him in a journey to the Underworld to retrieve Zeus's lightning bolt and prevent a catastrophic war.

The long-awaited prophecy surrounding Percy Jackson's sixteenth birthday unfolds as he leads an army of young demigods to stop Kronos in his advance on New York City, while the Olympians struggle to contain the rampaging monster, Typhon.

Uniting with Jason, Piper, and Leo after their dangerous quest, Percy, Hazel, and Frank wonder who will be chosen to fulfill the Prophecy of Seven, completing their group's number, and sail with them to an ancient land to find the mysterious Doors of Death.

When Apophis, the chaos snake, threatens to plunge the world into eternal darkness, siblings Carter and Sade Kane plan to use an ancient spell to destroy the snake, but first must rely on the murderous ghost of a powerful magician.

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.

In response to an awful camp orientation video created by the god Apollo, Percy Jackson and other residents of Camp Half-Blood answer campers' questions such as "What is this place?" and "Do I get to keep the T-shirt?".

"Percy Jackson, now a high school senior, needs three recommendation letters from the Greek gods in order to get into New Rome University. He earned his first one by retrieving Ganymede's chalice. Now the goddess Hecate has offered Percy another 'opportunity'--all he has to do is pet sit her polecat, Gale, and mastiff, Hecuba, over Halloween week while she is away. Piece of cake, right? Percy, Annabeth, and Grover settle into Hecate's seemingly endless mansion and start getting acquainted with the fussy, terrifying animals. The trio has been warned not to touch anything, but while Percy and Annabeth are out at school, Grover can't resist drinking a strawberry-flavored potion in the laboratory. It turns him into a giant frenzied goat, and after he rampages through the house, damaging everything in sight, and passes out, Gale and Hecuba escape. Now the friends have to find Hecate's pets and somehow restore the house, all before Hecate gets back on Saturday. It's going to take luck, demigod wiles, and some old and new friends to hunt down the animals and set things right again"--Dust jacket.
