The Book of Boredom

The Book of Boredom is a cursed magical tome of indeterminable and seemingly endless length. Nothing about it is particularly exciting - it isn't bound with human flesh, adorned with dragon bone or anything like that. The cover is perfectly average leather that shows the expected amount of wear and tear (no matter how much its owners might wish to abuse it, this never changes). The pages within, other than remaining indestructible, are normal pages. The ink written its really horrid pieces of prose and awkward poetry is not blood or magic or scrawled in mad ways, but just a sort of bland, black ink. The writing is legible and technically proficient, without standing out in any way. There are no scrawled messages of mad visions among the margains
The exact content of the Book varies, but it is always some sort of fictional story. Every genre has been reported, from horror and epic war stories, but they all have a tepid and uninspired plot with formulaic structure and uninteresting characters. Often, the stories contain irksome plot holes or inconsistencies - just enough to be noticeable, like a mosquito bite. Each story is attributed to different authors, though the names seem to be fabricated.
Unfortunately, any who begin to read the Book soon fall under its curse. The Cursed find themselves unable to put it down and will continue to red, insisting that "it has to get better, it can't really be this bad" - but it never does get any better. Readers will keep reading until they are incapacitated by hunger, thirst or frustration, at which point the curse is broken. Some readers can't help but to try again, though. That can't be all there is to the tome; there has to be some sort of secret message, or prophecy, or something. Right?
(No.)
It isn't known who first made the book - or why. Most blame the trickster gods or sinister conspiracies, but mage-editors fear the truth to be something more along the lines of accidental enchanting by a particularly amateurish mage. Exactly how the fresh stories keep getting into the Book isn't known either, but everyone wish it would stop. The Book has so far resisted all attempts to destroy it, making it by far the most interesting part of the Book.
Wizards in the know sometimes use the book to play pranks on each other, either covering the title up or masking its magical aura, then giving it away. Friendships have been permanently damaged by these sorts of jokes, funny as they might have been.
