Hmm... Half way through the book I wanted to rate it three stars for a plodding plot, but I decided to round up after I finished it. I personally have no problem reading long books (besides them being too heavy to lug around), but I felt that TMBS could have been a little shorter and to the point, without all the extra fluff. 
 Other than that, though, I found this book refreshing and original! It was nice to read something that wasn't a rip-off recycled plot from another book- maybe that's just a YA thing. Reynie, Sticky, Constance, and Kate, our heroes and heroines, have distinctive personalities that add to the story. I admire Stewart's ability to execute flawless plot twists (view spoiler)[(I especially loved how Milligan turned out to be Kate's father and the explanation for his name) (hide spoiler)] and little riddles that make the reader think. 
 Overall, this was a very cute story that I would recommend to a friend looking for something new.
