This has possibilities. It could be tightened about fifteen percent further, and you have some stylistic jags that deserve the attention of a seriously tough editor, but on the whole, it’s well done.
Thematically, it’s a bit obscure. Your scene-setting works acceptably well, but Ryska’s emotional bonding to the dead Luka isn’t quite clear enough to make her response to Toma completely credible. Beyond that, the reader is guaranteed to want to know how Ryska came to be what she is, as well as who she is, and you provide approximately no information about her origins. We must assume that she started out wholly human and was cyber-engineered into what she is now...but why was she selected for that procedure, and by whom, and were the facilities that treated her pre- or post-apocalypse? Are there others of her sort? If so, where are they and how was she separated from them?
All the same, for a SmashWords story, it’s a five-star accomplishment. Now go back to your word processor and complete the novel that so unusual a character and so striking a setting deserves!
