I'm sorry, but I cannot finish this for the life of me. Every second I read it I feel like stabbing a pencil through my jugular. It just drags on and on, going absolutely nowhere. Ever heard of the "one step forward, two steps back" mentality? Yeah, that applies to the plot of Crepuscule.

The worldbuilding is fantastic. Especially in the beginning, it just hits you all at once. All the characters, like Setz and Lark, initially amazed me (sometimes with their stupidity). The characters were developed, the plot expanded, conflict introduced, all that good stuff.
The problem is how annoyingly long the development took. It was over 100 chapters before a major part of the plot was introduced. A conversation could take 10 chapters. Moving from point A to point B could take 5 chapters. If all the filler was taken out, Crepuscule would be reduced by half.

Depending on how patient you are, this is worth it. The plot is unique and contains things that you would never even guess at. The characters will stick in your head for a while. But if you cannot stand insanely slow development, stay away.
