Children of the Mind gained a lot of traction in the second half. Orson Scott Card really stepped up, as I expected.
The largest section of each character arc arrived in half two. They were very cool. I didn't exactly foresee them, but they were properly foreshadowed.
Plot-wise, tons of stuff happened. The events were tense, contemplative, and satisfying all at once. Card is a master of his craft in this regard.
The setting comment from the midpoint analysis stands.
Children of the Mind earned an A- overall. There were some problems, but nothing unforgivable.
