Query: One of the saddest books I've ever read

This book was unlike anything else I've ever read. It was incredibly tragic and haunting. It made me feel for those women like Sunny, the ones who became nobody, because their minds couldn't get out of the past yet their bodies moved on through time. It really is haunting and although I didn't like it at first, because it was an unusual style for me, I grew to appreciate it. It's powerful and sad, and wonderful, too.
