Prophecy of Fire — Michael G. Thomas

Prophecy of Fire is the fifth book in the epic series set in the Star Crusades universe that chronicles humanity's first steps away from Alpha Centauri and beyond.

The fragile Centauri-Helion Alliance is being tested to the limits as Alliance ground forces under the command of General Daniels deploy on Eos, a strategically placed moon. Three complete regiments, including whole units of Jötnar and Vanguards assist Helion government troops against Dictator Lyssk's insurgents and their violent mercenaries. Jack Morato and his comrades are thrown into the bloody insurrection that is filled with suicide bombings, improvised explosives and roadside ambushes. The weeks of battle has cost both sides many lives, but it is a battle that must be fought if the worlds of Helios are to be ready.

After an arduous journey, Spartan has finally reached Alliance space only to find panic and bloodshed. Unidentified ships attack stations and vessels with impunity, and the few military forces remaining seem impotent against such power. It is the shutdown of a number of Rifts that causes the greatest consternation, however, as entire planets are cut off from one and other. The pattern repeats in dozens of locations as the Rift generator stations power down after the unknown ships travel through them, their final destination unknown. 

In the middle of all this confusion comes the great comet. This vast chunk of rock and ice appears to change course and a grand Helion fleet moves to intercept it. No sooner does the blazing comet arrive that the enemy finally reveals himself, and not a single world or colony is prepared for what is to follow.

Star Crusades Nexus is a classic work of realistic military science fiction set against the background of the Centauri Alliance's expansion into the Orion Nebula. Also available is the prequel series, ‘Star Crusades Uprising' set two decades earlier and covers the events of the Great Uprising that brought humanity to the brink of destruction.
