Jane Eyre so far?

At the start of the book I really wasn't intrigued at all with the book. Lavender kept calling it a "page turner" but I wasn't seeing it. It wasn't until the book switched from Lowood to her new life as a governess that book became interesting. So far the best part of the book has been chapters 15 and 16. Once the odd and unexplainable events started to take place the book became hard to put down. After Jane saved Mr. Rochester I was left wondering who was the cause of the fire. Was it just Mr. Rochester's carelessness? Maybe, but I still believe this event has more to do with Grace than anything else!
