This is neat.
You created the characters and their relationships right away giving a detailed description of how they are and act leaving little to no blank space.

Ah, this reminds me of The Great Gatsby and Gone With The Wind (for some unknown reason). This is definitely a writing style that fits the atmosphere and scenery. Short, but filled with image and explanation that gives the story the guidance it needs.
For this being a genre that doesn't really intrigue me, it really helped me recall the dots of what I have read previously of this style and made connections to sense what is about to or may happen which is nice because I can feel the intensity of the characters minds and actions and the story-line (so far) and this is just the first chapter.
Many more "wants" await the readers ahead for the next chapters to come along.
