Mystery Flowers — Grace Livingston Hill

After her mother died, lovely Diana Disston sought comfort in prayer--and in the single flower a stranger dropped daily on her pathway. But when her father married a jealous young wife, Diana fled in despair. Alone and penniless in a strange city, she went from one menial job to another. Miraculously, like a gift from God, the flowers followed her. And when Diana lost all hope, suddenly the mysterious flower person appeared--for he was truly the answer to her prayers.
