Brooklyn Pierce has made some bad decisions in her life, but the one that really gets her attention is the one that lands her in the back of the police car in the middle of the night. She realizes that she needs to figure out a new system for making better choices. So she starts a blog and conducts polls where her readers tell her what to do. She ends up in a number of situations that she would never have imagined: trying out for the rugby team, joining the debate, club, etc. In the process she makes new friends, loses some old ones, and learns a lot about herself, her family, and what is really important.
I heard this witty author speak a few weeks ago. The reason she writes these books is because it is what she wishes had been available when she was a young teen reader. Her characters are utterly believable. Plot is a bit predictable but not in a bad way.
