Hi LisMoniz!
I never saw that book before, but i found this information from Tibia.Wiki:
This item's name and category (Creature Product) suggest it was meant to be dropped by

Misguided Bully and

Misguided Thief which drop no creature product and were implemented on the same update as guidebook. This is believed to be an Unobtainable Item.
I will search a bit more information and edit my answer later, in case I find something about how to obtain it!
