In terms of the Enders Saga I feel that this book is set
apart in how much and how plainly it is a coming of age story. Also, for the
first time in the series the protagonist is both far more flawed than hero and
has a lot to learn. In some ways this is both refreshing and also not quite as
satisfying.
The story does a good job of expanding the Ender universe in
terms of what was going on after the third formic war and what becomes of
Battle School. We also get a lot more insight into the ongoing communications
between Hyrum Graff and Andrew Wiggin.
If you are not a fan of the series or the universe there is
not much for you here though.
