It is a classic Space Opera that takes place in a vast Empire led by a evil Empress with lots of different aliens. It is one of the most entertaining scifi series I have ever read. It is not a serious Science Fiction series, but taking the best of space opera to the extreme. It starts fast and never slows down. Each character is larger than life with unbelievable battle skills.
What makes it perfect sword and laser is that the the "laser" guns are powered by energy cells that need 2 mins to recharge (why is discussed in first book). So one shot then you must fight with swords. But this is only the beginning.
There are 3 types of enhanced soldiers (Wolflings (part man/part wolf), Haden Men (Cyborgs) and Dead humans with artificial blood (not zombies), large starships & space battles, Clones, ELF's (ESP'er Liberation Front), battle drugs, deadly aliens, deadly plants, deadly planets, a deadly Arena, and it goes on and on and on and on. I can not express enough the insanity of this series. It is so much fun!
I suggest starting with the Deathstalker series first, and then if you want some more background on a few characters, read the prequels. And if you still love it and can't get enough (like me), then read the sequel series.
Once you have read the series, yes, the name of my website is taken from these books. Have fun!
