Review Detail of HeartRend in Emross Empire : War And Order (Eng-V.)

Story seems interested, but the Synopsis is just a mess. Its confusing and does not accurately represent exactly whats going on. All I picked up was that he gets trapped in game, becomes emperor, somehow takes game army to real world and fights world government (who again somehow did something called a "soul harvest") and then somehow wins. Is that the whole plot of the book explained or is that everything before the book even starts?
