The Trials of Apollo, The Hidden Oracle. (First Book.) Storyboard creator: Madison Gaines. Book author: Rick Riordan.
The god Apollo falls from Olympus as a mortal, Lester Papadopolos, as a punishment from Zeus, Apollo's Father. He was punished for (unintentionally) helping his (roman) descendant, Octavian, start a war with camp half blood.
The conflict of this story is man versus self and man versus nature. Apollo is upset he is a mortal and wants to restore his former glory. He always doubts himself and isn't used to mortal life, and is extremely afraid of dying. The woods are also "speaking" to other campers, including Apollo, and luring them (besides Apollo) into the forest only to find themselves lost and wrapped in cocoon-like bandages as hostages.
The theme of the story is, that you don't know what someone else is going through until you go through it yourself. This applies to Apollo; being a former god, he always thought mortals were weak, puny, and a lot of other things. Now, being a mortal, he is feeling sympathetic and amazed towards human beings, as he travels with Meg Mcaferry, daughter of Demeter, the grain and crop goddess, whom is also Apollo's friend and Demigod Master.
