Twelve-year-old Percy Jackson is on the most dangerous quest of his life. With the help of a satyr and a daughter of Athena, Percy must journey across the United States to catch a thief who has stolen the original weapon of mass destruction — Zeus’ master bolt. Along the way, he must face a host of mythological enemies determined to stop him. Most of all, he must come to terms with a father he has never known, and an Oracle that has warned him of betrayal by a friend. 

 When Thalia’s tree is mysteriously poisoned, the magical borders of Camp Half-Blood begin to fail. Now Percy and his friends have just days to find the only magic item powerful to save the camp before it is overrun by monsters. The catch: they must sail into the Sea of Monsters to find it. Along the way, Percy must stage a daring rescue operation to save his old friend Grover, and he learns a terrible secret about his own family. 

 When Percy Jackson gets an urgent distress call from his friend Grover, he immediately prepares for battle. He knows he will need his powerful demigod allies at his side, his trusty bronze sword Riptide, and… a ride from his mom.

The demigods rush to the rescue to find that Grover has made an important discovery: two powerful half-bloods whose parentage is unknown. But that’s not all that awaits them. 

 Percy Jackson isn’t expecting freshman orientation to be any fun, but when a mysterious mortal acquaintance appears, pursued by demon cheerleaders, things quickly go from bad to worse.

Time is running out for Percy. War between the gods and the Titans is drawing near. Even Camp Half-Blood isn’t safe, as Kronos’ army prepares to invade its once impenetrable borders. To stop them, Percy and his friends must set out on a quest through the Labyrinth.
