Reading

I've been reading a novel by Patricia Cornwell. It's the latest novel of a popular series featuring the heroine Dr. Kay Scarpetta, a medical examiner. I like this series very much and I had read all of them. Last month when I was on the train, I saw a billboard of this book. After getting off the train, I went to a bookstore and bought it straightaway.
Actually I hadn't read a long novel for ages. When I thought about it, I realized the reason I haven't read any books recently. I quit my job two years ago, so I haven't had time to commute by train. I tend not to read at home. My reading time equaled my commuting time. Now I've been reading the book but at a very slow pace. I read it in the bathroom! LOL. I can read a few pages at once. When will I finish reading it?
