All for All – Christopher Nuttall
A satisfying ending to the trilogy. The author tells a good story while avoiding the traps to which space-combat-sf story-telling is prone: Exposition is largely avoided. Descriptions of battles do not get mired in details. The story is told from a modest number of viewpoints.
The larger story also manages to adhere to a limited objective: Victory is not defined as “Our little world defeats their evil galactic empire”, but as “Earth got out of this without being destroyed”. And it does.
