Revenge of the Alien Bugs. Invasion Planet Earth, #7

Captain Josh Miller woke and realized he was on his private starship. When he went to sleep, he was in the living room of his hacienda and could faintly hear his wives talking. His personal robot woman Coco told him that she had detected a bomb so beamed him out of there.  She told him his entire large family had been killed. The Alien bugs had almost been wiped out by military tactics that Captain Josh Miller had developed so they had reason to hate him.
The Alien bugs had gotten their revenge against him though. Coco and Josh walked out on the smooth surface where the hacienda had stood; he fell to his knees and sobbed from his loss. The Alien bugs had set a trap that transported him and Coco to an alternate universe. He had only a small family there since things had happened differently.  He hadn't developed efficient ways to kill the Alien bugs so humans were losing the war.
This set him on the path to fighting the Alien bugs again and having new adventures. This is book 7 of the Invasion Planet Earth series.
