The Disreputable History of Frankie Landau Banks

I loved 99% of this book.  The ending was left so wide open, I am praying for a sequel. The exploits of Frankie Landau Banks have obviously just begun.  Infiltrating the top secret society of her prep school as a sophomore leaves two more years to create havoc.

Why should we care?  Frankie is out to take down the "good old boy" system.  She knows where the power lies and with her keen eye for strategy and detail, I am sure she can find some new icons to overthrow.  I am also dying to know what happens in several of her unresolved relationships.  Author E. Lockhart has left the second semester wide open and too many characters hanging.  I want/need to know more.

The book trailer doesn't do it justice, but here it is anyway:
