In 1990 or so, I read a children's book about a little girl who discovered live people in a dollhouse. I believe the little girl was living with relatives following a tragedy in her family. The dollhouse was behind a wall, or something like that, and the tiny people inhabiting it were actually alive. In this book, there was a poem about a rose. That's all I can remember. I adored this book, and I hope to find the title of it soon. Thank you so much!
