I listened to this on audiobook, but only when my friend was with me so it took a long while to get through. This is not a book where all of the characters are lovable, the flaws were front and center here and people are mostly motivated by wanting knowledge/power. There are some lofty discussions of scientific/philosophical topics which are interesting but can sometimes make the story drag. Not much happens besides the Six studying and interacting with each other, then at the end the plot all rushes forward and just as it's getting exciting the book stops there. Hopefully this is promising for the next book, but it leaves you feeling a bit cheated after spending so much time reading this one.
