Today I will give a theme and summary for the more recent chapters in the House of Hades. What has happened is that the Argo II sneaked its way through Italy and managed to get to Bologna, but the ship was invaded by two dwarves and they stole the Archimedes sphere, among some other things. They are chased by Leo and Jason, and are eventually caught and forced to distract the Romans in New York.
         The theme for these chapters is there are always positives for things that seem negative, because they sent the dwarves to steal weapons and stuff from the roman army. Another thing that came from the dwarf ordeal was the book and the astrolabe which most likely will help the demigods' later.
