Probably not then although Toni Morrison won a Pulitzer for Beloved. To fall back to an old standard, To Kill a Mockingbird is probably your best bet. Huck Finn is always a good American literary standby and age appropriate, but An American Yankee in King Author's Court is another Mark Twain winner. The Hobbit is pretty good if she wants to go fantasy, but Dune by Frank Herbert is just as good from a literary point of view IMO and is one of the best selling Sci Fi novels of all time.
Edith Wharton is for the most part an excellent writer and story giver. I've never gone wrong with her works. Ethan Frome is good and a fairly short book so that might appeal to your daughter if she'd rather be doing other things as vacation time winds down.
The Outsiders by S. E. Hinton
Frankenstein; or, The Modern Prometheus by Mary Shelley
I'm not a fan of Graham Greene's The Power and the Glory and the definitely unlikable, unsympathetic Whiskey Priest. It's readable... and pretty short.
But The Quiet American is a great mystery and the book helped me during a very difficult time after my friend passed away in 2009.
As for the other writers? I've only read Haiku: This Other World by Richard Wright (my personal favorite book of poetry). Not sure if that can qualify as a readable book here.
MacDonald, George - has anyone read him - I see he writes fantasy books
