When the admissions office of Witch Academy called, I was stunned—I had been accepted into a school I never imagined I could touch.Yes, I am a boy and it is an all-girls’ academy, but they did not mind, so I saw no reason to object. I had applied secretly, without telling my family, just to take a chance.But as soon as those striking seniors greeted us newcomers—pressing every boy against the wall with a knowing smile—I realized things were about to spin out of control.“Oh, come now, you sweet little freshman,” one of them said smoothly, her voice full of mischief. “Don’t make this difficult for me, your big sis. Swallow this core and transform into a witch like me, alright?”She held the glowing orb before us, half-threatening, half-teasing, almost inviting the new boys to react. It was clear she enjoyed it—the blend of fear and resistance in their expressions. Our unease seemed to be her personal amusement.After all, they only had this opportunity once a year.
