"Since you're going to become one anyway, I may as well get it over and done" Samantha snapped, lifting her right hand, which had a strong flame burning from her palm. Before you or Harry could utter a word, you started to glow.
"What are you doing to me?" you squeaked, suddenly frightened and wishing you had obeyed mom's warnings.
