The ending wasn't really a cliffhanger. Like, yes they're in trouble, yet know they made it ( somehow), but it wasn't as open as Lost Hero and Son of Neptune. Also, like the characters didn't interact as much, like it was everyone in their little groups, and the descriptions of people, moods and relationship could have been more thouroughly described.
