I bought this book a long time ago and now I can't find it anywhere and I don't remember the name of the book or the author. But in the book I remember a single mother in her mid 40's moves in with her mother but she doesn't move in alone. She has a 21 year old and a 3 year old grand daughter moves in as well. She finds a job and starts trying to work her way up to saving money and getting her own place but there a lot of problems going on at hime. Her own mother has health issue's due to smoking a lot and she tries to help her mother quit. In the mean while her 21 year old daughter is out of control, she's never home to take care of her 3 year old (often leaving her with random friends so she can go out) she has no job, and she expects to get whatever she wants. Does anyone know what book I am talking about?

Can you remember any character's name or a town name or something even more concrete? You might want to call your public library and ask for reader's advisory. They have print and database resources and indexes (specific keyword searches) to help figure out questions like this.
