Lynne is reading in a library. This is because she thinks that if she doesn't get out of the house then she feels she won't have done anything productive. She could quite easily read at home but then she would be unlikely to get dressed. Besides, she has been recommended a book and wants to check it out.
The book she is reading is called Lumberjacks. What we don't know is whether it is a novel or a non-fiction book. It would be surprising if Lynne was reading an information book about lumberjacks so we can assume it is a novel. In it, a family of lumberjacks fall out over logging permits causing tragedy. This is as far as Lynne has got but the book is so gripping that she has read almost half of it at the library before taking it home. Unfortunately for her, the copy she is reading has a printing error, causing two pages to be completely blank. Luckily it has not upset her enjoyment of the book.
If this incident happened anywhere else, the librarian lady would be giving Lynne a piece of her mind for being unhelpful and rather juvenile. However due to strict library rules, the librarian must keep quiet so all she can do is stare in disbelief at Lynne. Lynne has broken the quiet rule herself by shouting Timber so the librarian is well within her right to throw Lynne out.
