I loved, loved, loved this book. I just started actively reading in August and since then I've read lots of wonderful books. However, I must say that this is the first book I've read where I simply could not stop reading because I loved it that much. 
 Then plot itself isn't all that original. Someone else described it as a combination of Groundhog Day and Mean Girls and it really is. However, the writing is excellent and there is a lot of genuine originality brought into the book through the side details. The characters are wonderfully done and I found myself caring very much what happened to them. 
 I especially loved Kent and any interaction he had with Sam. Too cute.
