Hi,
I am trying to earn this achievement. I have already read 5/8 books and now I am stuck. I keep checking last 3 locations but always the same fake book appears. About 15 times in a row it is "To do today", "Danger of the Abuse" and "Journal of the Archmage Antonidas", each book always spawns in the same place. According to WoWWiki there are 5 possible books to spawn in each place so it is strange that I always find the same title so many times in a row. Also, the book after having been read should disappear after 3 minutes, but I perceived that it it does after only 1 min.
Is there anything I can do to find a real books or everything works properly and it is all about the probability? It is really strange, because I read 5/8 first day and I have so big problem with those 3 remaining books.
Thanks for help

I haven't even started to complete this achievement bro, because I have to mentally prepare for that amount of time... :D Btw I think it works properly, because if you check the armory->achievements, you can find a lot of players with mostly fully completed achievements.

thats the one with the dalaran books right? I would check the other locations as well I don't think its scripted blizzlike.
