15-year-old Princess (New York teenager) Mia Thermopolis is back once more in her third hilirous diary of her life! During this time in her teenage life Mia has got everything anybody would want! Shes got a boyfriend, Kenny, fame, and on top of that Princess of Genovia! So you would think Mia would be pretty happy right? WRONG! Kenny is definitely NOT the right guy for her. Micheal, Lily's brother, is the one she has always wanted. However everything seems to go wrong and now she is trying to aviod further smooches with Kenny. And now Micheal is going out with somebody who is definitely more intelligent that Mia and most likely can clone fruit flies. On top of that her mother is now pregnant with her stepfather's baby. Oh yeah, did we mention that Mia's stepfather is also her Algebra teacher? And guess who has been failing algebra for a long time...? Plus, Mia has got the added pressure of preparing a speech for her nerve-wracking entree into the Genovian society. Things aren't looking to good for her. Maybe Lily can turn things around when they hatch a plan to get Micheal back.
After reading the first two diaries Mia wrote I couldn't wait for this one and it didn't disappoint me! Mia is still her old self with her sassy and funny humor which makes you laugh out loud. This book also had some emotional parts in it too which grips you. All and all a great book! It definitely lived up to my expectations. However I heard that this will be the last of Mia. I really hope that isn't true though. I recommend this book to all teens who love to have a laugh of two!
