The Trials of Apollo 4 books set By Rick Riordan

The Burning Maze

He was a God once. Until he was cast out his father, Zeus. Now, he's an awkward teenager. Called Lester. The only way out is a series of scary and dangerous trials, of course. For his third trial, Apollo must journey through the Labyrinth to free an Oracle who only speaks in puzzles. Then, defeat the most vicious of three very vicious Roman Emperors. (All without the use of his godly powers.)

It looks like he will need all the help he can get - from some new and old friends.

The Hidden Oracle

He was once an immortal God. Now, he's a teenage boy called Lester. Apollo has angered his father Zeus for the last time. So, how do you punish an immortal?

By making him human. Obviously. Cast down from Olympus, he's weak, disorientated and stuck in New York City as a teenage boy. It's the first time he's been without his powers, and he has to survive in the modern world. Which isn't an easy feat for a four-thousand-year old deity, especially one with as many enemies as he has. Apollo needs help, and he can only think of one place to go . . . an enclave of modern demigods known as Camp Half-Blood.

The Dark Prophecy

He was once an immortal God, now he's an awkward teenager. Things aren't going well for Apollo. There's only one way he can earn back Zeus' favour, and that's to seek and restore the ancient oracles - but that's easier said than done. Apollo must head to the American Midwest where, rumour has it, a haunted cave may hold answers. There are a few things standing in his way though. The cave could kill him, or drive him insane. Oh, and a Roman Emperor, whose love of bloodshed makes Nero look tame. To stay alive, Apollo needs the help of a mortal goddess, a bronze dragon, and some familiar faces from Camp Half-Blood. Will he survive the greatest challenge of his four thousand year existence?

Camp Half Blood Confidential

A companion guide to THE TRIALS OF APOLLO series, set in the world of PERCY JACKSON. Camp Half-Blood FYI is the funny insider's guide to the demigod training camp in Long Island, narrated by none other than Percy Jackson himself, and other favourite characters will be heard from, too. In response to an awful camp orientation video created by the god Apollo, Percy Jackson and other residents of Camp Half-Blood answer such questions as "What is this place?" and "Do I get to keep the T-shirt?"

Newbies can check out the section on the Divine Cabins, read up on Magical Landmarks, and consult the chapter of Training Arenas. But Camp Half-Blood Confidential explores much more than just the buildings and grounds. It includes info that can only be learned from those who live there. For instance, campers do not always co-exist in peace and harmony. The camp is not run with superior efficiency. Prophecies do not flow forth with great regularity. Sprinkled throughout are stories from heroes who have called Camp Half-Blood home or just passed through on their way to places unknown. Chiron himself introduces the book with a brief history of training based on his millennia of experience. And, of course, divine words of wisdom from the god Apollo himself are included, because the demigod authors would prefer not to be struck down by him, thank you very much.
