I had never read a road-trip novel before, only saw movies which I found quite boring. That's why the travelling part of the book surprised me positively. I found myself enjoying the "little detour" as much as the characters to the point that I'm beginning to think that such a road trip through the USA will be a good alternative for my vacation. 
 The rest is just Amy and her grief. It's easy to figure out what her problem with driving is from the beginning and at some point it was annoying to see how she could open to other people but not to Roger. At the same time it felt liberating every time she got a step further, you could be happy for her and that felt right. I loved Roger - ex-girlfriend obsession included. He's cute and funny and cuddly. All the people they found in their journey made the book special, interesting and worth the reading. 
 The book is about a girl recovering from her father's death, about how important it's to talk about what's troubling you and it's about grief and how overpowering it can be. A&R may not be the most romantic story I've ever read, but it's one of the most special ones.
