Undiscovered Gyrl
I probably can't talk about this book without spoilering it, so proceed with caution, especially Danna, to whom I am going to mail it as soon as it's safe to go back to the post office. (i.e. after Santamas)
The first back of the book blurb likens the title character to a 21st century Lolita, but I think she's more similar to a blogging Go Ask Alice.
