You've woken up as the opposite sex this morning...

Now what?

Hogwarts was the sort of place were accidents happen all the time. You can't expect to keep hundreds of young, untrained witches and wizards in one spot without at least slight mishaps.

This particular accident, however, was a little bit different.

***

It happened on an apparently ordinary January day in her sixth year. She woke up slowly, enjoying the feeling of being safely enfolded in the canopy of her bed. It wasn't until the other girls in her dormitory also began to wake up, and the screaming started, that Luna realised something was amiss.

Her voice, when she asked what was wrong, was a lot deeper than she remembered. And her hair was shorter, too - there was none of the familiar weight on her shoulders.

When she scratched her cheek, she realised that there was even a faint trace of stubble on it.

Not feeling particularly worried - more intrigued - Luna made her away across the dormitory, past her frightened roommates, and studied herself in the mirror.

The figure looking back at her, although dressed with some difficulty in Luna's patched and frayed night gown, was definitely not the one she remembered. It was taller, more muscular (although not that muscular), and, most importantly, male.

"Oh," said Luna. One of the girls gathered behind her almost fainted.

Luna sat patiently in Dumbledore's office, her legs over the edge of the armchair she was seated in.

She'd met the trio in the Great Hall on the way to breakfast. Luna had a Charms lesson at 9 o'clock, and didn't think that changing gender was any excuse to miss it. Harry, however, had persuaded her to go and see Professor Dumbledore first.

He'd kept a remarkably straight face when he told her this (Ron hadn't been so polite), so Luna had been all too happy to obey.

Professor Dumbledore, when he'd found her waiting patiently by the gargoyle for him to return from breakfast, had kept a straight face too, though he'd been rather sat to inform her that it might take a while to locate a counter spell.

She's still wanted to go to her lessons, but the Professor had insisted Luna remained here, for some reason.

Humming to herself while she waited, Luna decided she was rather glad she wouldn't have to get used to this new anatomy. She didn't really like it very much. Later, she'd have to ask Harry, Ron and Neville how they coped.
