In The Mark of Athena by Rick Riordan, Annabeth Chase is out to avenge her mother.
Their quest is even more complicated now that Annabeth has told the Argo II's crew about the sliver drachma.
Percy doesn't want Annabeth to leave him again on her quest but he'll have to make that sacrifice.
Leo was told by the god Nemesis that he's the seventh wheel in the quest. Nemesis says that Leo will have to make a big sacrifice, and she can help him for a price.
Jason is questioning his leadership along with Percy, and they don't know how they're going to defeat the twin giants.
Hazel's and Leo's lives are being messed up by their mysterious past, and relationships are changed in their time on the Argo II.
As for Piper and Jason, Piper has to worry about what Achelous told her about the sons of Zues and Jupiter, including what Hercules told them before he got hammered by coconuts.
In the book The Mark of Athena, Rick Riordan "Ham's up" the story with six million dollars' worth of gold, dolphins afraid of Diet Coke, Spiders making giant chinese handcuffs, and giants that like ballet in destruction.
