Second man strategy psychology.
Card has done something rather impressive here and taken his superb novel Ender's Game and approached it again from the angle of the second most important character.
It details Bean's history, as well, growing up as a runt kid in Europe, near-starvation, and getting by in gangs on his brain alone.
You get to see the psychology of the young man as he goes through the same training programs, but as a far more streetwise and self-aware individual than Ender, the military leaders have decided to use him as a backup and support mechanism, while letting him more in on what is going on.
