Wreath by Judy Christie

What do you do when you’re too young to be on your own but have no one to turn to? Sixteen-year-old Wreath Willis makes a list: Find a place to live. Buy cheap food. Finish high school. Get a job. Go to college. Now she’s finishing high school by day and squatting in a junkyard by night, flying below the authorities’ radar while she makes a few awkward friends and searches for an illusory “good life.” But when a teacher grows too suspicious, Wreath is afraid she’ll have to move on before she graduates. Could it be this was a good life? (synopsis taken from Goodreads)
