Kama felt the word like a stone warming in her pocket. "If it holds things," she said, "what does it want from me?"

Word spread beyond the stairwell. A woman with a scarred thumb came with a small box of letters she had saved from a soldier at sea—proof she had loved and then had been abandoned. She asked for closure. The Blume produced a petal that smelled of salt and answered the woman aloud in a voice that sounded, impossibly, like two people at once. She walked out of the apartment with a new gait, eyes reddened but clear. A man came asking for wealth; the plant gave him a coin that directed him to a thrift shop where a painting he had loved, long gone, hung by chance; he sold the painting and paid debts for a small while. Sometimes the trades were merciful. Sometimes they were cruel in ways no one could predict.

"Eva Blume," she said. Her voice scraped like an old hymn. "May I come in? I know better than to stand on thresholds."
