4.5

 This book was really great for what it was. Keep in mind, it's a feel-good (or heartbreaking/sad depending on which point you're at) book. Nothing that's going to make you think or change your world. But for what it is, it was so good. I'm not even a big dog person (I can't believe with what they put up with!) but even I started to fall in love with Marley.
