“An Unexpected Boon” by S. B. Divya, Apex #102 November 2017, fantasy short story
(Apex is on a roll, with a recommended story in the last issue and another in this.)
The viewpoint of this tale shifts a bit between Aruni and Kalyani (a brother and a sister) the latter of whom seems to have something like a pronounced Asperger’s Syndrome. She’s very smart but can’t read expressions well or stand to be touched by people. When the parents leave Aruni in charge for a time while they’re away and a sage arrives, Aruni is extremely worried because (Indian?) custom dictates that Kalyani must serve as hostess. Much to his surprise, things go well and Kalyani is given a boon – a magic beetle (lightning bug, I think) – because she asked for a friend. When a second sage arrives, however, things do not go well at all and he curses the home. The siblings’ handling of this curse, and its ultimate effects, fill the remainder of the tale.
Aruni is sympathetic as the caring, but exasperated, brother, the milieu and the lightly (and then heavily) fantastic elements are well-handled, and the contrasting sages are intriguing, but Kalyani steals the show. Her disabilities and struggles and compensating extra abilities (even before her beetle kicks in) are well-drawn and induce, but don’t unfairly coerce, the reader’s affection and the working out of the ecumenical parable, while familiar, is satisfying.
