At last a book where normal and plain are not used as synonyms for stupid and boring. Besides being clever and nice, the heroine has a nice sense of humor without being (too) snarky. Not much angst or hesitations with her : she's not gullible, and she's able to put her beliefs in perspective when the facts don't match them. In fact, she's the embodiment of common sense, and being ordinary is her superpower ! 
 The whole story is ingenious and ridden with clever ideas and anecdotes that flow seamlessly into the plot. I Felt sometimes like I was caught between Working Girl, The Twilight Zone and Disneyworld, and strangely, I liked it a lot. Must be the magic ;).
