Rosencrantz & Hemlock by Kira Butler
When I visited Yaga’s apartment, I didn’t really believe in magic — and definitely not the really black stuff — but I did know one thing: you could totally put a price on revenge, and I was ready to pay with my life savings if it meant never having to endure another week of those bitches posting stuff to my Facebook wall where mom could see it. I thought the old lady would scare them, you know? I thought maybe six months’ worth of allowance would cover it. I’ve never been more wrong.
