Castle Federation Universe
The Castle Federation series is a far-future transhumanist space opera where the Terran Commonwealth, driven by their vision of Unification, are determined to bring all of human space under the rule of Earth.
They were stymied thirty years before by the forces of the Alliance of Free Stars, a multi-national force led by the Castle Federation and the Coraline Imperium.
Now, after three decades of cold war, the Commonwealth is moving again...
The series focuses on the development of Kyle Roberts from a relatively low-ranking Commander, Air Group, to the architect of the operation that turns the tide of the war and the choices and sacrifices he and his comrades make along the way.
