Outside Reading

I am reading Metamorphosis and so far it is pretty good. This kind of book wouldn't normally grab my attention but since it's a short book(I'm not a very fast reader) and got really great recommendations from a lot of people so it was an obvious choice for me. At first this book was sort of slow and hard to get into, but after about twenty pages it started to speed up and the story is starting to grow on me. For example the start of my book began by talking about the protagonist's family and working life which was not very appealing to me, but after that the plot became very interesting.
At this point the dominant literary element in my book is point of view because, it's told from the main character's perspective and well...the main character transformed into a bug. Because of this he tells the story from the point of view of his whole family not being able to understand him, and him trying not to scare them whenever they see him. So far I'm pretty sure this is the obvious literary element, but i wouldn't be surprised if it changed later on in the book.
I think the author is using this literary element dominantly in the book because that is the only way to give the reader the same trapped, helpless feeling the main character is experiencing. Also if the book wasn't written this way i don't think it would be nearly as interesting because I'm not used to this style of point of point of view, but I am used to most other styles of point of view.
The tone of this novel uses fairly neutral diction making the tone a bit boring at times, but overall fairly gloomy and a little bit hopeless as the main character struggles to remind himself of his human past as he becomes more accustomed to himself as a bug. So far the tone hasn't shifted at all over chapters because the protagonist has been a bug the whole book. I'd be surprised if the tone shifted at all through the story, but maybe it will change at the climax.
