Read about this one on Monica Jackson's blog last week.
Naughts & Crosses by Malorie Blackman is a Young Adult novel that explores the theme: what would the world be like if "blackness" was the norm, and everyone and everything had to live up to that standard.
The novel is the first in a trilogy exploring the characters and theme in Naughts & Crosses. And it has earned a slew of awards and critical acclaim.
For you aspiring writers, by the way, the Young Adult market is hot. Especially fiction for and about youth of color. Many publishers are looking to expland their Young Adult lines. And many authors who made their mark in writing for adults are now turning to Young Adult fiction to expand their writing abilities and also their audiences.
Cynsations has a great blog entry (and blog) on breaking into Young Adult fiction.
Anyway, I think the Naughts & Crosses series might be a good thing for you or a young adult in your life.
