The first page of the ancient book required for the Book for Tognasher quest is located in The Steppes and is a ground spawn in the grove. It is a challenge, not because it is really hard to see, but rather it is rare and not in the same spot (except for being in the grove).
Eventually I gave up looking in bushes, following satyrs and trying to work out the location coordinates and just ran around. After a relatively short while I found it.
It looked like this:
I had unticked Allow 2.0 Pixel Shadows and unticked Radial Flora (aka Showgrass) under Advanced Options in the Display tab.
Good luck finding it.
