jedimaster573:has brought this to my attention that this achievement is now starting to glitch on people its starting to end up like borderlands dlc wear collectibles glitched on ppl when it first came out

naughty died :but if you reload your game and pick the last book up again, it will pop up....

Didn't see a video guide up for this yet so I figured i'd help out.It seems that if you play co-op with anyone before you get these achievements it will glitch your achievements. Just play alone or wait for an update just to make sure.
