The Trials of Apollo - The Dark Prophecy

von Rick Riordan

Apollo and his companions seek the ancient oracles - restoring them is the only way for Apollo to reclaim his place on Mount Olympus. Somewhere in the American Midwest is a haunted cave that may hold answers for Apollo in his quest to become a god again...if it doesn't kill first. He will need the help of a now-mortal goddess, a bronze dragon and some familiar demigod faces from Camp Half-Blood.
