As it was published in 1931, I think it should be public domain, still looking for a copy, though.
Pearl S. Buck died in 1972, so the book is NOT public domain anywhere.
An ebook version was released last year by Open Road, so you should be able to find it in all the ebookstores. Overdrive has it, so some public libraries should have copies.
