Mercy


Catherine Miller - 2016
    Unwanted. Outsider. Such are the slurs cast upon Rykkon, however undeserved. As the only village healer, his people cannot cast him out entirely, but there is little comfort in such a life when he has long known that no mate from his clan would willingly join with him. It is a lonely fate, but one Rykkon has learned to accept. That is, until one tense exchange between his people and the humans brings him an offer he simply cannot ignore. The humans are not their slaves. Nor their property. Nor of any great concern. But neither are they free. It is by the provisions of the Arterians they scrape out a sorry existence in the Wastes, and by their goodwill alone that they continue to survive. Scavenging for hasart beetles under the two suns is the only life the desperate colonists have known since their ancestors first landed on the desolate planet. It was all they knew. It was all they hoped for. Until one day, a young female dares to ask for more. --- “Wait.” The entire group stilled, staring at him as he continued to regard the female. She glanced up sharply, her brow furrowed and her gaze cautious. As right it should be. “I will take you for a mate.”
