Wow, I'm really impressed by this story. It's one of the best I've read on GA for a while. Your characters are well-written and real, even though we see them through Elijah's somewhat harsh eyes. Your dialogue is refreshingly natural and the pacing in your narrative works really well. Your descriptions of the psychological environment and reactions in the story is especially good. You resist the temptation to be too obvious or cliché and write with an affinity and sensitivity that indicates either personal experience or excellent research.
I'm impressed by your style. I like the sensitive, at times even florid prose you use and even more I like how wonderfully you control it with Elijah's more stark or laconic observations. The constant swing between the idyllic and the uncanny (for lack of a better term) has become to me an integral part of Elijah's personality. There are some absolutely wonderful turns of phrase, especially in his cynical deconstructions of the people and social connections around him. The section about Mr. Alders in chapter 8 is so far a personal favourite.
One should always temper one's praise with something more critical and if I had to point out some (albeit very minor) flaws, I would advise you to be more sparing with your adjectives. If you use them too much they tend to lose significance. At least be very aware of how you apply them and contrast it with Elijah's acerbic and succinct wit (as you have so far succeeded in doing).
I read everything so far in one sitting and can't wait to read more.
