The full title essentially tells you everything you need to know to book talk this to students: Spare Parts: Four Undocumented Teenagers, One Ugly Robot and the American Dream.
4 Mexican American teens from Arizona take on some of the brightest students in the country in a robot building competition. The book will be published in December, 2014, but early reviews make it a must-purchase for school libraries. The movie trailer will definitely spark some interest in the book. Appropriate for grades 7 and up.
