I can remember reading this book some years back and giving it 3 stars but just rereading it while listening to its audiobook has really made me enjoy it so much better. 
I think what put me off the most about this book back then was Cybil and her bubbly personality but I find that I enjoyed her way more than Preston this time around. You kind of get to know, understand and connect with her way more than you do with him.
I think I’d definitely be reading this book again in a couple of years.
