I liked this book, but I did not LOVE this book. Just One Day is about a this girl who goes on one of those teen tours around Europe, and is just about to go home when she meets this guy who offers to take her to Paris, since that city was canceled on the trip, for just one day. It's about so much more than that but that's all I want to say about it. I really liked the character development in this story, and how she learns so much about herself. I'd give it an 85%, because I didn't really like the boy she meets.
