Into the Darkness — Raymond L. Weil

For over six years, the Lost Fleets have been trapped in the Triangulum Galaxy. Every day has been filled full of danger as the galaxy conquering Simulins search relentlessly for them.

With the arrival of the Distant Horizon, a daring plan is made. A message drone would be sent back home to give them warning of the deadly danger the Lost Fleets are facing. A danger that would soon boil over into the home galaxy as well.

In the heart of a massive star cluster, Admiral Jeremy Strong learns the Simulins' greatest secret. A secret that is so dangerous it could mean the end of all civilized life.

Back home Admiral Race Tolsen waits for a Simulin attack. An attack that the politicians in the Human Federation of Worlds don't believe will ever come. But Race knows better, all the evidence points to an imminent invasion. An invasion he doesn't have the forces to stop. He will need a miracle, but miracles sometimes are hard to come by.
