She wants to be my friend...what's the catch?

I really liked the strength of the main character, Kate, in Hot Girl by Dream Jordan.  Kate is fourteen, and after getting moved from one foster home to another, her life is finally settling down - she gets along pretty well with her foster parents, her grades are good, and she's got a great friend, Felicia.  After Felicia goes on a trip for the summer, Kate's on her own.  She's not sure why she's befriended by super stylish fly-girl Naleejah, but Kate's not complaining when the make-over Naleejah gives her catches the eye of Charles, Kate's long-time crush.  Something is up, though, and if Kate can't keep her actions under control, she's liable to lose the stability her current foster home is finally offering.  What is she willing to risk?  The voices, thoughts, and conflicts in this book are wonderfully authentic and the character development is great.  A super book, especially for older middle school to high school girls.
