I know you won’t read 'em all, so I gave you short summaries to help you decide on most of them. 
Their Eyes Were Watching God – Zora Neal Hurston (woman’s independence from man)
Fences - August Wilson (father and son)
(upper two are African American…just finished the class)
Ender/Bean’s Series – Orson Scott Card (at least Ender’s game. I love that book!)
The Blithedale Romance - Nathaniel Hawthorne
Catcher in the Rye - J.D. Salinger
(here’s a tip. I read this book and had to go back for the AP test and review it through sparknotes. I learned SO much from sparknotes it wasn’t funny. After you’re done, and you want more of something, see if it’s on sparknotes, etc. )
If you want shorter for a break (ha!) (as in short tales in one big book,) check out The Canterbury Tales by Chaucer
Crime and Punishment -Dostoevsky (title is pretty summarizing – man’s punishment for his crime, both internal/external)
Death be not proud - John Gunther (Sad, about a young adult with a terminal illness)
Diary of Anne Frank
The Giver - Lois Lowry (vastly different lifestyle from what we know, futuristic)
Hachet -Paulsen (story of a lost boy’s survival in wilderness)
I never promised you a rose garden (story of a girl with a mental illness)
Walden - Thoreau (non-fiction, he describes his then way of life alone in the wilderness)
The things they carried - o’brien (vietnam story, non-fiction in the sense that the writer went to the war, fiction in most sense in that the concepts of truth and falsehood are major here)
Scarlet Letter -Hawthorne (adultery and its affects)
the red badge of courage (war story)
raisin in the sun - hansberry (african american struggles in Chicago)
Pride and Prejudice - Jane Austin 3 daughters and their pursuits of men.
The Pearl - Steinback (novella, really, short and simple words (6th grade level on purpose) but good message.
these next two are also novellas and easier reading, but deep if you search - Of Mice and Men - Steinback, Old Man and the Sea - Hemingway (parallel of his writing career - the sharks are his critics)
Paradise Lost - Milton (heavy reading. epic poem in heroic couplets regarding the human fall)
Moby Dick - Melville (an obsessive man’s desire to capture a whale)
These are of course NOT all the books I could write. I could go on…forever… dreamy look
of course my summaries are possibly flawed, lacking. It’s been years for some of these books. forgive me.
