What's the Name of That Book??? discussion

This was a young adult paperback book I read circa 2003 about two teenage girls who discover the houses of fairies or gnomes in a yard. The cover featured some kind of gnome or fairie houses on it. One of the girls was very poor and I remember the other girl seeing her gathering cans on the side of the road to cash in for recycling. The poor girl lived in a house without electricity and her mom was mentally ill.

This book had a 1970s/1980s vibe. I remember it being strangely depressing. It was found in the library of an elementary school.

Thank you!

Afternoon of the Elves by Janet Taylor Lisle. There are several different cover illustrations, depending on the edition.
