Finished reading “Demon Star (Star Force Book 12)” by B.V. Larson and David VanDyke, first published August 3rd 2015.
Goodreads Three stars, three worlds, three civilizations…one massive war. In a triple star system, not all planets are equal. When the DEMON STAR swings closest in her orbit, the Insectoids always invade. They raid the inner worlds with grim regularity, riding hordes of stealthed ships in ever growing waves.
