So. Fourty-one books huh?

Alright so, I'm trying to read more books that aren't just the funny Japanese picture books and thought to myself \*House of Leaves sounds fun\* then I saw a snippet of Death talking about dead cats drowned in a well on a topcharactertropes post and thought \*oh this looks neat, wonder what Discworld is about\*

Little did I know that there would be over 40 books with different sub series and stand alone stories and good god I have no idea where to start please help me
