What is a pulitzer or Nobel Peace Prize winning novel that is short, around 200-300 pages, OR read below for other suggestions you can give me....

It's hard to know exactly what you mean about
"entertaining." There are any number of books that are riveting, for one reason or
another.

A Hundred Years of Solitude
by Gabriel García Márquez is a highly acclaimed book, as is Joseph Heller's
Catch 22. Harper Lee's To Kill a Mockingbird
is a little over two hundred pages, and is a classic of American literature.
The Godfather by Mario Puzo was also a highly-read book when it was
published. Another is In Cold Blood by Truman Capote, but this book
is "hard core" and often hard to take, based on actual events. If you like sci-fi,
Michael Crichton's Andromeda Strain might be to your liking: in
fact, anything by Michael Crichton is probably good—he's an excellent writer. This
particular novel is from the 1960s. The Autobiography of Malcolm X: As Told to
Alex Haley by Malcolm X, Alex Haley is a book that drew many readers and
still does today. The Graduate by Charles Webb might be more
entertaining that some of those previously mentioned. Rosemary's
Baby by Ira Levin might entertain if you're into witchcraft and
exorcism.

Books that I found entertaining, that were
considered risque at the time, though I'm not sure they are two hundred pages in length
(they might be) are the Ian Fleming series of James Bond books. I thoroughly enjoyed
them, and there are several to choose from. I recall that I liked Casino
Royale a great deal. For mysteries, you might check out Agatha Christie
novels. Another mystery is Marnie, by Winston Graham. Up
the Down Staircase by Bell Kaufman might be an entertaining, humorous choice
for you. One more classic is One Flew Over the Cuckoo's Nest by Ken
Kesey. (The novel is both humorous and tragic at the same
time.)

There are many other books. Some are more for a
younger audience like the Lloyd Alexander books, and there are many. Chitty
Chitty Bang Bang by Ian Fleming is also entertaining, for a younger audience
but I'm not certain about the length.

There are many to
choose from. I hope I've been able to provide one that meets your
requirements.
