Read the excerpt from "Seventeen Syllables.”

"Gee,” said Rosie. Natsu, who never said much and when she said anything said it shyly, fingered the coat covetously and Haru pulled it away.

"Mine,” she said, putting it on. She minced in the aisle between the two large beds and smiled happily. "Let’s see how your mother likes it.”

She broke into the front room and the adult conversation and went to stand in front of Rosie’s mother, while the rest watched from the door. Rosie’s mother was properly envious. "May I inherit it when you’re through with it?”

Haru, pleased, giggled and said yes, she could, but Natsu reminded gravely from the door, "You promised me, Haru.”

Everyone laughed but Natsu, who shamefacedly retreated into the bedroom. Haru came in laughing, taking off the coat. "We were only kidding, Natsu,” she said. "Here, you try it on now.”
