Request #636 From MJ

My friend MJ is looking for a book from her childhood.  Here is what she
says about it:

“I loved a book when I read as a preteen/teenager probably between
1992-1995. I remember (hopefully correctly) that it was about siblings
who became homeless orphans. They joined a little group of other
homeless orphans who taught them homeless kid magic. While dumpster
diving they taught the main character, a girl?, to visualize what she
wanted and convince herself it was real, and then she’d find it in a
trash can. The girl visualizes a pair of roller skates, lifts up the can
lid, and finds one. She is disappointed, and thinks she can’t do much
with one skate, until she finds it matching mate in another trash can
further down the street. She learns to trust the homeless orphan magic
and the book continues.

I feel like this book has been hard for me to find because that was
maybe not a pivotal scene in the book? It was particularly meaningful to
me. I was raised a witch, and I’ve continued to practice witchcraft in
my adult life, and this was the first explanation of manifestation magic
I came across in a children’s book.

Whenever I ask a friend about it, not only do they not remember, but
they say it sounds like a really sad book. I don’t remember it as being
so, and I remember it being sweet and one I really enjoyed.

Thanks for any help in advance!”

She adds:

“It wasn’t sad, I promise!”

Thank you and your readers for any help they can provide.
