Defying a witches heart

will Hester ever be vulnerable to love?, does she even have emotions?, or is her heart just pure darkness?, could she ever fall in love with her best friend?, or maybe a mysterious new boy at the school?, maybe they kiss, or maybe she throws him out the window.
heck she might even fall in love with sophie? (just kidding about that last one, could you imagine Hester and Sophie? over my dead body)
can anyone reach her heart?
( do not recomend this if you havent read book 3, in that case you should go read it right now cause its fricken awesome)
(on another note, please ignore the fact that the witches should be on their quest and not at school)
