The Color Purple

Hey people! So just yesterday, I started reading this book called The Color Purple by Alice Walker. So far, it's been pretty interesting. But I'm still confused when it takes place. Most likely, I think it's in like the 1800s or something cause they talk about women like they're slaves. Can anyone tell me? Also, I want suggestions on some cool books to read this summer! I asked my cousins and they're on the same page as me. I'll be interested in any books. Thanks people!
