The girl beside the window looked up. She had straggly, waist-length, dirty blonde hair, very pale eyebrows and protuberant eyes that gave her a permanently surprised look. Harry knew at once why Neville had chosen to pass this compartment by. The girl gave off an aura of distinct dottiness. Perhaps it was the fact that she had stuck her wand behind her left ear for safekeeping, or that she had chosen to wear a necklace of Butterbeer corks, or that she was reading a magazine upside-down. Her eyes ranged over Neville and came to rest on Harry. She nodded. ‘Thanks,’ said Ginny, smiling at her. Harry and Neville stowed the three trunks and Hedwig’s cage in the luggage rack and sat down. Luna watched them over her upside-down magazine, which was called The Quibbler. She did not seem to need to blink as much as normal humans. She stared and stared at Harry, who had taken the seat opposite her and now wished he hadn’t. ‘Had a good summer, Luna?’ Ginny asked. ‘Yes,’ said Luna dreamily, without taking her eyes off Harry. ‘Yes, it was quite enjoyable, you know. You’re Harry Potter,’ she added. ‘I know I am,’ said Harry. Neville chuckled. Luna turned her pale eyes on him instead. ‘And I don’t know who you are.’ ‘I’m nobody,’ said Neville hurriedly. ‘No you’re not,’ said Ginny sharply. ‘Neville Longbottom – Luna Lovegood. Luna’s in my year, but in Ravenclaw.’ ‘Wit beyond measure is man’s greatest treasure,’ said Luna in a singsong voice. She raised her upside-down magazine high enough to hide her face and fell silent. Harry and Neville looked at each other with their eyebrows raised. Ginny suppressed a giggle.
