One of the most difficult things when you were trying to navigate the world of books was dealing with all the unreliable authors. They were so unbelievably tricky to keep track of. An author might write a brilliant book, only to follow it up with something utterly mediocre. Or, and this was almost worse, one might have written a brilliant book but then turn out to be dead. Then there were those authors who started a series but never finished it.
