I read a new English book. It`s called "The last song" by Nicholas Sparks. When I first saw the cover of the book, I thought that this book is a story about love and holidays. The sundown in the back is one thing, that makes the cover even more interesting and shows that this is a very romantic and touching novel. What do you think is this book about?
