The environment is a mix between mountains and grass lands. This mix gives it a calming and some anxiety to because someone or something could be lurking around the corner.
The book is pretty crowded because there is many city's and camps filled up with people. It makes me feel like in the end all the people are going to do something amazing.
Some object are the Athena Parthenoes which a statue which has the power to keep it self protected while getting more enemies to destroy it. Then the house of hades which belong to the god of death himself hades the Greek side of the death god.
It helps a lot because without this the book who seem boring and I wouldn't read it at all. The parts that help the most is the landscape it help me imagine what's happening chore clearly. The overall mode is pretty mysterious because sometimes a strange creature or items. The atmosphere is in an adventurous because this whole book is about a great adventure, which makes me want read more of the book.
