Fulgrim

No spoilers. I want to preface by saying that as I haven’t finished it yet.

Ok so it’s not really to do with the story but didn’t know where else to post it.

So I’ve just seen after trying to find a replacement fulgrim. That there are some books which have different (I think called blurbs?) back covers basically. So on my book which I currently have it starts with “It is the 31st millennium..” I won’t do the whole thing as I’m sure you guys have seen it. Then I was looking through eBay at people selling Fulgrim and their back cover is different to mine. (I personally prefer the one I currently have as it feels way more exciting) There one is like kinda saying the same thing obviously because it’s the same book but it’s shorter and imo not quite as exciting as the one I currently have.

So my questions I guess are what’s the difference between them if there is any? Is one more rarer or something? If I order a new fulgrim (which I have) which back cover will it be?

(I know it’s not really that deep at the end of the day as it’s still the same story but I’m just curious about it.)
