Very intriguing start. I hope to read more of it. I really like how you ease into it as a storytime without really telling anyone what is going on and the fact that there are aliens. It is an interesting concept that, quite frankly, I personally have never seen before; the man of two realities. 
The story feels very alive and promises mystery and adventure, however it sometimes gets confusing with the referencing of time: she said or she says etc. Nevertheless, I would, based on what I've seen so far, definitely recommend it and hope to see more of it soon.
