This book is perfect for teens and adults. I think it would pair greatly with the classic that it is based on. It's almost reminiscent of Gilmore Girls...with a hint of Mean Girls. It covers important topics that do need discussed so it'd be great for a mother daughter read.
A friend that hadn't read Wuthering Heights read it and she admitted some of stuff confused her because she wasn't familiar with Wuthering Heights so I highly recommend pairing it with Wuthering Heights if you haven't read it (or at least watch a movie version. There's a version starring Tom Hardy. *swoon*).
