Whisper by Alyson Noel
Book Four of the Riley Bloom Series
Just when I thought Riley was getting a little more maturity, a new book starts and we are back to the same issues in the first three books. "Wahwahwah I wanna challenge" and then "Omg I can't do that are they insane".
I was very frustrated and debated on whether or not I should even bother finishing it, but it's only two hundred pages or so. Part way through the Riley realized that was exactly what she was doing. And she had a big inner battle about it. Things got better and I really enjoyed the end of the Riley Bloom Series.
The very end with the birthday party was my absolute favorite part I think of the entire four books. Messalina was a refreshing character, who I greatly enjoyed!
