That's a random assortment of pictures in your avatar, Gryphor... XD
Heh.
Rincewind? Hm... so that's the series which the Discworld series was based on?
Well, it's not that bad, for a book composed entirely of diary entries, business logs, letters and bits of printed news. Never mind the fact that a person in predicaments like theirs would probably (hopefully) not actually waste time writing in diaries while they were faced with possible death(s). Though they remember an impressive amount of dialogue, for being in those situations...
It gets kinda boring when women are getting all chummy in their happy little, "My dearest, forgive me for taking so long to write, I have so much work to do. So how is your romantic life? Have you many suitors?" letters. Right after the "Might die, vampires are after me." part.
Also, the guy can take a page and a half to run in circles tossing words around in a somewhat random, repetitive manner.
He's trying to be suspenseful, that's fine, but he says the same things multiple times, sounds like he's finished at, "All right, let me be factual." and then continues circles for another half-page. He stops doing that quite as much toward the end, though.
Other than that, it's not bad.
Did you read it? Or would you just be saying that due to the time it was written?
