Not even that... H&I's relationship has been non-existent for a few years and was never properly developed anyway (unless you count the series, which most don't, for good reason)... but now they've all just buddied up and it's pillow fights and giggles? feh.
I have faith in Dini not to write it like that, but the book concept is kinda flawed in this way.
Also schoolgirl uniform? COME ON. Harls is about as subtle as a mallet to the head, but she's not predictable - or so mundane. Cliche and it doesn't work for her. Damn, 90% of my income is made off the back of schoolgirl fantasies. It's TOO BORING for Harley.
