“I was friends with them for a while,” she said finally, talking into her chest. “We had fun, running around in the woods. We were wild. We’d hurt things together. We killed a cat once. But then she”—as always Adora’s name went unsaid—“got all interested in them. I could never have anything to myself. They weren't my secrets anymore. They were always coming by the house. They started asking me questions about being sick. They were going to ruin everything. She didn't even realize it.” Amma rubbed her shorn hair harshly. “And why did Ann have to bite . . . her? I couldn’t stop thinking about it. Why Ann could bite her, and I couldn’t.”
She refused to say more, answered only in sighs and coughs. As for the teeth, she took the teeth only because she needed them. The dollhouse had to be perfect, just like everything else Amma loved.
I think there is more. Ann and Natalie died because Adora paid attention to them. Amma could only view it as a raw deal. Amma, who had allowed my mother to sicken her for so long.
Sometimes when you let people do things to you, you ’re really doing it to them. Amma controlled Adora by letting Adora sicken her. In return, she demanded uncontested love and loyalty. No other little girls allowed. For the same reasons she murdered Lily Burke. Because, Amma suspected, I liked her better.
You can come up with four thousand other guesses, of course, about why Amma did it. In the end, the fact remains: Amma enjoyed hurting. I like violence, she’d shrieked at me. I blame my mother. A child weaned on poison considers harm a comfort.
