This book is hilarious! I love Georgia, she is just a little self-absorbed, but aren't all of us at that age? ;) Her observations and friends are just too funny.
This edition contains the first two volumes of the series: "Angus, Thongs, and Full-Frontal Snogging" and "On the Bright Side, I Am Now the Girlfriend of a Sex God". I'm not sure why they call it the "adult" edition, there is no harsh language or "adult" scenes. It is perfect for the middle school or even high school age would find it amusing.
