NOT a rating I had expected to give a book this late in the series, but what can I say? I'm a geek and I LOVED it. I even did all the math problems along with Stacey (and got them all right, thank you very much - DIAL-A-CALCulator strikes again). I also appreciated that Stacey didn't get all stupid about spending time with her dad, but ended up making (mostly) the right decisions.
