In The Hidden Oracle, when Apollo lands on Earth, he gets immediately ambushed by 3 thugs in the alleyway that he crashed in. When he makes it to a refuge, known as Camp Half-Blood, he discovers that the thugs were sent by the Triumvirate, a shadowy group of 3 nameless ancient Roman emperors who have been returned to life and are trying to once again wipe out the Greek and Roman gods and demigods. They've secretly been manipulating how things have been going for the demigods the entire time, and they need to be taken out.

How do you think Apollo, without his powers and communication with the other Greek gods, will take out 3 essentially immortal emperors? More importantly, who are the 3 emperors, and why are they trying to ruin everything for our protagonists?

Who are the 3 emperors.

I would actually read this book because it is action and adventure.
