It was amazing to go back into Mia's world after, for me, nearly ten years and still remember her character and her world clear as day. I recently (two years ago) tried to re-read the books that I had missed and found the earlier ones nearly unbearable from an adult perspective, excepting the tenth one (which I LOVED). I like that Meg Cabot has continued on with the more mature tone/issues from the tenth book while keeping Mia still as hilarious as ever, evidenced by my frequent laughs out loud! I especially love how she kept all the old pop culture icons that we know Mia is obsessed with (Buffy, Star Wars, Britney) while adding in some truly unexpected and glorious mentions of more recent stuff, including a very memorable Game of Thrones joke. 
 Mia's still got it - this was such a fun read, and I am so thankful that I have something of Mia's to read and re-read that doesn't make me cringe about my own teenage years. Only one thing to say: SQUEE!
