The Hidden Oracle by Rick Riordan is the first in his series “The Trials of Apollo”. This takes place after the war with Gaia in previous books. Apollo has been blamed for causing the war by allowing himself to be flattered and caught off guard. Zeus punishes him by sending him down to Earth as a mortal for the third time in his immortal life. However, he quickly learns that this time, he did not retain any of his godly powers as in previous times. He is claimed by Meg McCaffrey, a demigod child of Demeter. Apollo finds her very rude and annoying, but because of his punishment is forced to become her slave. Apollo is forced to go to Camp Half-Blood and must learn to accept his mortality. He must also, with the help of his demigod children and friends, win back the Oracles that have been taken by the mysterious evil group the Triumvirate.
Riordan explains very well the thoughts of Apollo when he first becomes a mortal. He believes that he is still a god and should be treated as such. The protagonist is not a perfect being who is selfless and kind, but rather someone with many bad qualities. Apollo also consistently makes mistakes and has trouble adjusting to the new lifestyle. All of this allows readers to understand Apollo and relate to him, and the book can mean more. Riordan also finds many instances to add humor to the story, so it is not a dull and serious read. The entire style of the book is very informal, with Apollo as the narrator often talking to the reader instead of explaining what is happening. This is a fun change from the format of most novels. However, it slightly detracts from the actual story and makes it harder for a reader to connect with the book. The plot itself is nicely written, with numerous challenges for Apollo coming one after the other. Overall, this is a well-written book with a unique style and will prove to be a fun read.

This series is EPIC!!!
For those of you who don't know, there are five books. 1. The Hidden Oracle. 2. The Dark Prophecy. 3. The Burning Maze. 4. The Tyrant's Tomb. The fifth one, Nero's Tower, is supposed to come out October 2020.
This is a sequel series to the series Percy Jackson. That's pretty awesome too.
Summery:
The god Apollo has been kicked out of Olympus by Zeus, and is stuck on Earth as a mortal human, with no powers, named Lester Papadopoulos. He finds himself having to serve Meg, a demi-god daughter of Demeter, the god of plants. They have to go on quests to free Apollo's oracles, kill the three immortal, tyrant, Roman emperors who have somehow survived (yes, that includes Nero.), and kick the Python out of the main oracle's cave.
This is an epic five-piece adventure that I would recommend for 13 years old and up.

This book was not as good as the original Percy Jackson series in my opinion. Apollo was a spoiled narcissistic character, although he did improve later in the book. The story line was not as interesting. I think the younger generation of Percy Jackson fans will still like this book.

This is a great follow up to Percy Jackson. I love the premise of the series!! Also, it is so sad that people that people hate it because it has LGBTQ+ characters.

Yes, this is not directly about the book. Yes, this needs to be said.
For all those saying that LQBTQ+ characters are offensive, or abnormal, or no longer human because of who they are:
There is nothing wrong with loving a person who is the same gender as you. There is nothing wrong with being a different gender than the one someone else decided you were. It's not a choice. And there's nothing wrong with writing about people who this is true for.
There is nothing wrong with being who you are.

There isn't any offensive or innappropriate content in this book, despite what all these other commenters are commenting about. Apollo has been portrayed this way in mythology many times before.

However, this is still easily the most uninteresting and boring Riordan book I've read so far. Apollo and Meg were (in my opinion) unlikeable, snobby, or arrogant. While that's just part of their characters and personalities, it generally made the book not fun to read and hard to connect with the characters.

What a delight to return to the same universe as Percy Jackson and all the rest, but this time following one of the more unreliable narrators, Apollo, who has been returned as a mortal teen and forgotten as much as he recalls from being a god. The stakes are higher, although this adventure gets resolved, there's definitely more to come. If you like action and adventure, this one is for you

I honestly thought this was a pretty good book. I don't understand why so many people are getting hyped because of the homosexuality content. Reading this in 2020, it is normal to feel that way. I don't get why anybody would put a warning or say kids shouldn't read this book like it's bad for kids to know or read about this stuff. If you did put a warning or a comment related to that either your old school minded, or you're really young and immature. If you let this content effect hat you think of the book I think your pretty bias, I am not homosexual myself but I still respect them like I respect every other human and I think its time you all do too.

There are people that say that because this book has homosexuality that it is a bad book. The people that are homosexual are just like us, they are happy about who they are with, but some people disagree that they are normal (blue_bear_6565).Those people do not have friends that are homosexual, those who do know how much they get bullied. People, accept people who are homosexual they are no different than us. Now that is my opinion, that is not some peoples opinion. This was a great book. Would definitely recommend.
