Sunlight slants through the kitchen window, catching dust motes as you round the corner. Your parents stand beaming, and in your mother's arms is a little girl with blonde hair and grey eyes. She's smiling—but it's not a child's smile; it's knowing, almost sly. She reaches a tiny hand toward you, fingers curling as if beckoning. Your mom says, "Hey sweetie!
