I've read four out of the five finalists:
The Berlin Boxing Club, by Robert Sharenow
Between Shades of Gray, by Ruta Sepetys
Blood Red Road, by Moira Young (YES!!!!)
Shine, by Lauren Myracle
Under the Mesquite, by Guadalupe Garcia McCall
And now I'm off to ILL Under the Mesquite, which, HELLO!, I really should have read by now.
