I felt like this whole series was very slow during the middle part with lots of things happening that hindered the protagonists to get to their goal. At some points I kind of forgot which side quests were just on. And then suddenly a very anticlimatic and rushed end imo. Still the humor and worldbuilding of Riordan is really amazing to me. 

I am happy to see some kind of queer representation here, but they never even mentioned the words „queer“, „bi“ or „gay“. It felt a bit too safe, like something that a conservative person might be able to „overlook“. Let‘s be honest I would expect more from. a buch of greek demigods.
