The Hidden Oracle is kind of one of those books you’ll read just because you’re a huge Riordan fan (like me). The plot of is not the best; it’s the standard action/fantasy plot of a character fighting monsters with friends and maturing along the way, along with some good old-fashioned betrayal. It does have some redeeming points, though. First of all it’s written with typical Riordan humor. Also the story had a unique point of view, since it is about (and narrated by) the ex-god Apollo, who Zeus made mortal after his involvement in the war with the giants in the previous series. Apollo, of course, does not handle this well, especially after he is tied to the annoying demigod Meg and forced to go on several dangerous quests. This book is also a MUST read for Riordan fans because it ties off several loose ends from the Heroes of Olympus series and also has several references to the Magnus Chase series. However if you’ve never read any other books by Riordan you’ll be fine because the references aren’t major plot details.
