Hi, Hjolnai . I was cruising for a little reading for my coffee this morning and happened on your story. If (as you indicate) you'd like some feedback , well, here's a little; but first of all, I enjoyed the story - you captured my interest, pleasantly forestalling some precious moments, the dreaded double-click on a story I'm struggling too hard to write for the Recruiter's Office.
Replace 'finding' with another verb in order to indicate a separate 'find' - Worm. As it reads one might interpret that Sald found the library which was exactly 'who he sought' (?). Another verb, such as 'discover' might better separate the 'what' from the 'who'. All I'm saying is I tripped a little on it and other readers might lightly trip as well.
I know what you mean - kinetic, as in classical Newtonian energy as opposed to chemical or plasmic or whatever else energies are available. But your reader might appreciate a little reassurance on the matter, unless of course you've covered this distinction before and I just missed it.
Like I said, I'm just killing time and this feedback is 'picky' to say the least. Nice story.
