Pompidou Posse could easily pass as YA.

After runaways Sage and Vicky, aged 17 and 18 respectively, fail to make it as artists in Paris, they find themselves on the streets. A series of disastrous jobs later, the girls find themselves among the Pompidou Posse, a group of vagabonds and tramps, and experience all the hardships that comes with being homeless, such as running from police, drug abuse, and escaping from an axe-wielding maniac.

I have tried and tried and tried to get into the book. Not necessarily badly written but I simply could not connect to the story or the characters.
I will try it again the future, but, for now, I admit defeat.
