I tried that a few times aussie when Someguy029 gave me directions to a shard location. As I said ive read the book, found a shard, entered the ruins, spoke to the ghost and found her corpse. There is no journal on the corpse because the quest wont trigger to spawn it on her body. Ive reloaded multiple times in every instance Ive tried to force it along with no joy whatsoever.
I think that this may be your problem. You're not supposed to find
any shards until well after you talk to the Ghost and a healthy dungeon romp.
You read the book to kick off the quest, yes. But you found an Aetherium Shard out of order. This may be why the rest of the quest isn't triggering for you.
It's not likely since other quests just have the central character (in this case, the Ghost) say something like; "Oh, you already found -blah-, let's go look for-blah-."
This quest may not have had that option programmed into it thus it's throwing off the quest progression code.
