I loved it all... except for KC (not the character herself. The portrayal of the character from the mc's eyes). Could even swallow the Boy Next door going Demon on her ass. But what I cannot forgive is when your best friend says he's a good guy because he's only tormented you. I didn't like how the author pussy-footed around this. Girls of that age NEED some self-respect. In all things, Tate had self-respect except when KC was involved. They needed to truly talk that betrayal out. It was the worse form of role model when the author wrote Tate just accepting this as if it was her fault for not understanding what everyone else needed and wanted was more important than her wants and needs. This needed voiced, especially when she heard them speaking of it being all a trap. Girls need to learn to require more out of a life-long friendship- relationships. There was room to give a good moral for readers, but that was pushed to the wayside. When the girl who has always been at your side as you were bullied dates the bully... friendship over- for life. It's no different than if a grown woman friend dates someone that you had to have arrested for assault, imo. 
 ... just saying.
