Here's the Particle Horizon synopsis:
From the blood and dust of New Jerusalem, the Legion of the LightBringer wages a galactic war against those who would replace their god. Now, the time has come for the Union of Free Worlds to make a stand. The front line is the idyllic asteroid world of Angelhaven, where the greatest mind in human history has discovered an elemental power with far-reaching implications. A power that both sides will do anything to harness. Marine commander Gomes leads the crack Union task force. An unrelenting warrior driven by revenge and a need for answers, he hides a strange ability neither science nor religion can explain. On the other side of the war, Aja is forced to fight for a cause she doesn't believe in to protect her own secret. Caught between them is Una, a living machine who battles for her humanity as her world falls apart. Outnumbered ten to one and stalked by a mysterious nemesis, all three will play a role in unraveling Angelhaven's enigma. As the Legion invasion begins, unknown eyes watch with interest...
