Greetings!

No spoilers.

No questionable behavior that I saw, but that depends on your definition. There is a lot of political turmoil. A lot of groundwork set. A lot happening. And the children are getting older and more independent. Rebellious.

Good and evil are still relatively distinct - this is no more clouded than book 4 was. Perhaps a D&D type breakdown of good, evil, lawful, chaotic and neutral would be better. But there are scenes that show you that nobody is perfect, and a few illusions are shattered.

Darker, yes. Not Steven King, but certainly not book 1. Targeted at more mature children / teens. More grim, certainly. More suspense, yes. Lots of surprises.

A great read!
