3.5 
 I just laughed a lot with this book, until the point of tears. I mean, I enjoy weird literature and unusual scenarios, so, the hell and the way it works was really funny. I liked Maddison, I think that she was a great character in many ways, too mature for her age, but this book is not a serious one, so... 
 I got a little bit bored in some parts, when Maddie starts to overthink (maybe that is why it took me a lot to finish it), but in general, I had a great time with this one. Probably, I will read the full trilogy.
