So, I've only needed one book to complete this for the last month. I know all the spawn rates and spawn locations. The last book I need is on the bottom floor of the Violet citadel in the bottom left corner of the left most bookcase on the right as you come in I camp it and check it as well as reading and clicking on all books I see in all the other locations. I do this as often as a human can who has a job, wife, and 2 year old daughter can...my question: is this particular book any more difficult, or am I simply getting unlucky? I'm sure it's just luck, but I still want to make sure there isn't something I can do. Thanks in advance.
