The breeze of open air hit her, and her heart plunged. She skidded to a stop, flailing her arms wildly to catch her balance before Harry slammed into her. "Stop,  stop!" she screamed, and she heard bodies slamming into the wall to avoid knocking into her. Someone's hands grabbed Hermione around the waist to pull her in from the edge of the cliff as she grabbed for anything to hold on to. She was terrified of heights and the unfathomable expanse of dark beneath ran a pang of lightning down her spine and turned her perspiration cold.
