Would Pride and Prejudice or Emma work? They are girly/romantic, but simple issues, and possible movie tie-ins and discussion of real social issues, gossip, privilege, etc.
I am trying to think of what I read in 7-8th grade classes - not a lot of novels. Short stories. 9th grade we read Great Expectations, Romeo and Juliet, My Antonia.
Is she specifically looking for 20th century lit? How about Picture of Dorian Gray combined with The Turn of the Screw? They're both quick, fast read, fun and exciting, and the latter has a female protagonist (well, not necessarily admirable, but still) and has interesting things to say about ambiguous content / unreliable narrator.
Roll of Thunder, Hear My Cry
This was one of my suggestions! Along with The Secret Garden and A Little Princess (haven't heard a response)
Pride and Prejudice
They read it in 11th grade. My wife hates teaching, though, and the 7th grade teacher loves it, so maybe it could be negotiated.
Emma
Love it. Only Austen I actually don't despise. Don't know if 7th graders would get it quite as well, but worth suggesting.
My Antonia
My Antonia might be a good choice...
Picture of Dorian Gray combined with Turn of the Screw
They do Dorian Gray in eleventh grade along with Jekyll and Hyde (summer reading, so fast reads are good) which is an awesomely perfect pairing. I don't know Turn of the Screw, but I'll suggest it.
I don't actually know if she's looking for 20th century or American specifically. They do US history in 7th grade, so tie-ins can be nice, but I don't think its a necessity.
Peter S. Beagle's
A Fine and Private Place,
or
The Last Unicorn?
Hah, my first thought was also "Roll of Thunder"! Is
"Circle be unbroken" a sequel to that or something else? I don't think I've re-read them since middle school. Hmm. Westing Game? Might be too young.
Does
True Grit
have enough "literary heft"?
True Grit
I don't know, I've never read it! But I'll suggest it. Along with the Beagles.
I think Let the Cicle Be Unbroken is a sequel to Roll of Thunder, yes.
Good choice. Not that I've read it myself. Saw both versions, though.
Gris, is this independent reading?
For 7th grade, guided, I would do Merchant of Venice (and have!) Or the Crucible.
For book they read mostly independently, I'd suggest
I Capture the Castle
Peace Like A River
Shabanu
Little Women
Black Ships Before Troy
Life of Frederick Douglass
Adventures of Tom Sawyer
The Number Devil
If you are going to be implementing the Common Core, then I'd suggest they look for what the CCSS has in their curriculum maps. i only have the maps 9-12.
How about When I was Puerto Rican by Esmeralda Santiago. I taught that to low 10th graders.
