Help me out: Book for Roo

Help me out!

In each Ruby book, Roo is reading something for school that connects with her current situation.
She's read The House of Mirth  
and The Scarlet Letter  
both about women who are ostracized from their communities.

Now she is taking Contemporary American Literature. 
She is suffering from heartbreak (as usual). And interested in more than one guy (as usual). And has complicated friend issues (as usual). 

What should she read?   

Something that would be assigned accomplished high school students in their senior year. I imagine this class's reading list includes Beloved, Rabbit Run, Brief Interviews with Hideous Men, The Color Purple, and stuff like that.
