Year Adventures #1 The Chalice of the Gods (original) Rick Riordan

Percy Jackson, modern-day son of Poseidon, is just trying to get through high school. After saving the world multiple times by battling monsters, Titans, and giants, Percy is now settling in at Alternative High School in New York, where he hopes to finally have a normal senior year.

Unfortunately, the gods aren’t quite done with him yet. Poseidon breaks the bad news that if Percy expects to get into New Rome University, he will have to fulfill three quests in order to earn the necessary three letters of recommendation from Mount Olympus.

The first task is to help Ganymede, Zeus’s cupbearer, retrieve his golden goblet before it falls into the wrong hands. You see, one sip from it can turn a mortal into a god, and Zeus would not be pleased with that result. Can Percy and his friends Grover and Annabeth find the precious cup in time? And if they do, will they be able to resist its special power?
