Looking for some kinds of novel

Hi everyone!
I'm looking for 3 or 4 kinds of novels/fiction. I'm writing my Major Thesis and I need to find;
-21st century novels depicting the lives of latinos as immigrants in America.
-21st century fiction depicting the lives of native americans, the new challenges they are facing for this new millenium.
-21st century novels of muslims living in the US nowadays.
-Same for asians and blacks.
I would like to find novels like this with a particular focus on motherhood/women/family ( or not ) and ideally, they would represent the challenges and the issues they are facing in the 21st century.

Thanks for your help :)

These books refer to immigrant experience of South Asians, Muslims and non-Muslims.

Manju Kapur - The Immigrant (Indians, bu it's based in Canada)
Mohsin Hamid The Reluctant Fundamentalist (Muslim, Pakistani - about the dissatisfaction of a Muslim expatriate in the US)
Jhampa Lahiri - The Namesake (Indian experience of migration to the US) and The Lowland, which is another novel in the same vein.

I'll post more if I remember any other books.

The Brief Wondrous Life of Oscar Wao (2007)

thanks for those titles but i'm really looking for contemporary fiction ABOUT contemporary issues.
The reluctant fundamentalist is a good one, thanks :)

You might want to give Black Girl/White Girl, by Joyce Carol Oates a try... it's not exactly what you asked for as it doesn't focus on immigration, but it does have an interesting take on race.

Franzen's "Freedom" has an interesting Indian immigrant, who's the mid-life "love interest", and sub-ordinate, of the main character, Walter. She's an example of the upper middle class, globe trotting, very together, brilliant immigrant who is much better at furthering the cause of the environmental agency she works for than her deeply flawed boss/lover. Lots of current environmental/political issues dealt with here! (Big coal, over-population, bird conservation,etc, etc....) As you might expect with Franzen, motherhood/women/family are very much central to the novel.
