After the trio were sent on their great prophecy, they fly to Quebec to meet Boreas and his 3 children. I did not find this to be intresting as it was all talk and no action, and I am quite the fan of action. After this little event they were asked to kill all the storm spirits in Chicago before they could proceed to Aeolus (ruler of winds). At least this part was interesting as Piper and Leo were almost executed on sight but once they saw Jason, they realised to listen to them. Not much happened in these chapters, only fillers nothing else.
