This is another go talk to someone. Follow him to the dwemer runis solve the puzzles quest.
Only two places may cause problems on this quest.
When you're in the room where your on a bridge and the room is flooded and theres doors either side you need to unflood the room with the cubes. Kill the centurions. Then you only want one cube in at the top so the room is partially flooded.
Then down on the bottom level there is another pedestal. Put a cube in it the the steps appear so you can get at the higher door and go for the cube in there.
After that the whole room will flood so go straight across to the room with a broken walkway. The water level is now high enough to get through there for another cube.
The only other tricky bit is when you're in the room with three bridges you need to lower.
The only thing I can say about that is only use the left and right buttons. The middle one doesn't do anything.
After that its just grab the last cubes put them all in place and
grab the book. Achievement unlocked.
