Penguin Wish Me Dead

The funny thing is I never even meant the first one. Now I bitterly regret visiting the cursed witch's house, deep in the middle of the forest. It's where I made my wishes. I wished Klara Klein dead. It came true. I wished for the most gorgeous boy in town to finally notice me. It came true. I wished to be rid of the poisonous busybody who destroyed my family. It came true. I didn't mean for this to happen. Not me, Steffi Nett, the shy one who never says anything. But as the body count increases with every wish I make . . .who else could it be?
