This is a weird one. I'm kind of confused about the levels of different civilisations in this world. I'm also kind of ashamed for the sake of the Culture minds involved. They caused, though indirectly, a lot of deaths and destruction, for the sake of satisfying their curiosity. Not to mention I didn't understand, why did the septain or what was he, kill the president. Maybe I missed something.
I kind of want to learn the full name of the EOU Mistake Not... I like the characters in these books.
