Galactic Alliance (Book 3) - Honor Thy Enemy

Imprisoned by the Kyrra within a hyperdimensional barrier that warped space into an enclosed universe, the Chroniech applied all their intellect to finding a way out. After fifteen years they succeeded. Confident in their ability to break through the barrier, the Chroniech had been building warships as fast as their shipyards could produce them. With the barrier breached, the unstoppable invasion force descended upon the Alliance with one goal in mind - extermination.
