I can finish a one route in one sitting if it's really something fantastic, but a whole and long novel - never. I'm a little busy with my studies, so I can't spend all my time on reading. Indeed, I can spend my time on it on weekends, but I'm such a slooowpoke, so it's a bit difficult for me to finish even some short stories in one sitting, sometime. For instance, I was reading Eden* two days, and it took me a week to finish Cartagra (with all endings)!
