The Dark Prophecy was written by Rick Riordan.
Apollo has been cast down from the Olymp and found the hidden oracle in Camp Half-Blood. On his way to restore another oracle, so that he can return to the Olymp, he runs directly into the second member of the evil Triumvirate who kind of hates him after what happened between both of them in the past. Now Apollo, Leo and Calypso have to protect Indianapolis and find the second oracle before the time runs out.
I love Leo Valdez. I know that some people think he´s super annoying because of his many crushes on literally every girl he sees but you know, he has a girlfriend in this book so he´s not flirting with every girl he sees.
Apollo starts becoming more and more human especially when he´s trying to protect Meg. And what I really enjoy about Trials Of Apollo in general: You learn so much about Apollos past and since he´s my favorite god in all of Rick Riordans books I really appreciate this.
I can´t wait for the next book to come out.
