If you dont suicide you would get to both locations, the room with the holes is after the outside location where the first book is. You can also get to it by going right after the first group of adds in the trial instead of left, but very few people go that way
If I remember correctly, you can sneak to the one up the stairs from Yolnarkiin, and from there continue to the room where the other book is. I can't remember if you can sneak to the second one, because a couple of guildies were with me after we finished the trial. You will die a few times, but as long as someone else stays in the group after the trial ends, you should be able to get to them.
