Hearts & other body parts

Three beautiful witch sisters--Esme, Katy, and Ronnie--seem to have everything going for them. But two new students change the delicate balance in their high school. First there's Norman who isn't exactly the cutest guy--with his nearly eight foot tall body seemingly a hodgepodge of body parts connected together by bolts. But Esme finds her strangely attracted to him. On the other hand, Zac, who just arrived from the UK, has all the girls tripping over themselves. He's dangerously handsome in every sense of the word, but Norman is the only one who seems to notice that anyone who goes off with Zac alone comes back severely hurt, without their memories, or worse--they don't come back at all.
