The Trials of Apollo

1. The Hidden Oracle ©2014 ISBN 978-1-4847-3274-8 728/1000

     How do you punish an immortal? By making him human. After angering his father Zeus, the god Apollo is cast down from Olympus. Weak and disoriented, he lands in New York City as a regular teenage boy. Now, without his godly powers, the four-thousand-year-old deity must learn to survive in the modern world until he can somehow find a way to regain Zeus's favor. But Apollo has many enemies—gods, monsters, and mortals who would love to see the former Olympian permanently destroyed. Apollo needs help, and he can think of only one place to go . . . an enclave of modern demigods known as Camp Half-Blood.

2. The Dark Prophecy ©2017 ISBN 978-1-4847-4642-4 610/1000

     The second book in the latest series from international bestselling author, Rick Riordan

     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' favor, 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, rumor 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?

3. The Burning Maze ©2018 ISBN 978-1-4847-4643-1 781/1000

     The formerly glorious god Apollo, cast down to earth in punishment by Zeus, is now an awkward mortal teenager named Lester Papadopoulos. In order to regain his place on Mount Olympus, Lester must restore five Oracles that have gone dark. But he has to achieve this impossible task without having any godly powers and while being duty-bound to a confounding young daughter of Demeter named Meg. Thanks a lot, Dad. With the help of some demigod friends, Lester managed to survive his first two trials, one at Camp Half-Blood, and one in Indianapolis, where Meg received the Dark Prophecy. The words she uttered while seated on the Throne of Memory revealed that an evil triumvirate of Roman emperors plans to attack Camp Jupiter. While Leo flies ahead on Festus to warn the Roman camp, Lester and Meg must go through the Labyrinth to find the third emperor--and an Oracle who speaks in word puzzles--somewhere in the American Southwest. There is one glimmer of hope in the gloom-filled prophecy: The cloven guide alone the way does know. They will have a satyr companion, and Meg knows just who to call upon. . .

4. The Tyrant's Tomb ©2019 ISBN 978-1-4847-4644-8 102/1000

     The fourth book in Rick Riordan's The Trial of Apollo series.

     Things are getting very bad, very fast, for Apollo...

     The former God Apollo is having a pretty rough time of it. Well, for one thing, he's been turned into a human and banished from Olympus. And he's called Lester. But being an awkward mortal teenager is the least of his worries right now.

     Though he and some of his friends have emerged from the Burning Maze, rescued the Oracle, and lived to fight another day, they can't escape the tragedy that has befallen them, or the terrible trials still to face.

     So, with heavy heart, Apollo (OK, Lester) and Meg have a triumvirate still to defeat, oracles to rescue, and prophecies to decipher, so that the world may be saved, and Lester may ascend into the heavens to become Apollo once again.

     But, right now, Caligula is sailing to San Francisco to deal with Camp Jupiter personally, and they have to get there first. Failure would mean its destruction...

5. The Tower of Nero ©2020 ISBN 978-1-4847-4645-5 14/1000 (Could be 18 - handwriting is terrible!)

     It's time to face the final trial...

     The battle for Camp Jupiter is over. New Rome is safe. Tarquin and his army of the undead have been defeated. Somehow Apollo has made it out alive, with a little bit of help from the Hunters of Artemis.

     But though the battle may have been won, the war is far from over.

     Now Apollo and Meg must get ready for the final - and, let's face it, probably fatal - adventure. They must face the last emperor, the terrifying Nero, and destroy him once and for all.

     Can Apollo find his godly form again? Will Meg be able to face up to her troubled past? Destiny awaits...
