Percy Jackson i el calze dels déus

For once, Percy Jackson doesn't have to worry about saving the world. This time he has a much more difficult task: entering university. The University of New Rome asks for letters of recommendation from three gods to gain access, so... yes: Percy will have to carry out new quests to get them. First mission: The cupbearer of the gods, Ganymede, has lost his chalice, which is not only embarrassing, but could lead to disaster, since any mortal who drinks from the chalice will gain immortality. Percy, Annabeth and Grover must find the chalice and return it to Ganymede before anyone finds out what happened. These gods... they could put a GPS on their magic items, right?
