Space Marine in Star Wars

in the grim darkness of the far future, there is only war. during a trip through the warp on a mission to exterminate a rising tyranid threat, a battle barge is suddenly attacked by an entity of unknown origin. Brother Maximus of the Ultramarines, Brother Raxor of the Salamanders, and Brother Sebastian of the Black Templars are all lost to the warp, only to wake up on different planets in a galaxy far far away. This novel is more of a test to see how well it's received. If it's received well, and becomes popular, I'll keep writing for it.
