A/N: Okay, so this story is a collab between me and my friend Mhea (pinkpuppyx on wattpad). I write all the 'odd' numbered chapters (i.e, the 'Abbie' chapters) and she writes all the even-numbered chapters (i.e, the 'Mhea' chapters). The story starts January 2017.

Disclaimer: Neither myself nor Mhea own Harry Potter... Nor do I own Ultraviolet, which belongs to RJ Anderson.

Chapter One

Abbie

I yawned. Sunlight was streaming in through the curtains into the dorm. I sat up, rubbing my eyes.

My roommates were divided- two were sleeping, one was getting dressed, and one wasn't there. I yawned, swinging my legs over the edge of the bed.

"Morning Gabby," I greeted. Gabrielle Law nodded back, brushing her blonde hair. "Where's Mollie?" I asked. Mollie Foster was another of my roommates.

"Bathroom," Gabby replied, jerking her head towards the door leading to our en-suite.

"Sugar!" I hissed under my breath. I really needed the bathroom. Gabby sent me an apologetic look.

"She's in the shower," she told me. "She'll be done in five minutes…"

Silently cursing Mollie, I sat down on my bed and pulled a book from under my pillow. Despite being at Hogwarts with all the interesting books, the wizarding world didn't have any decent fiction. I always brought five or six books with me on the start of term, and would then send them home with an owl and a letter specifying which one I wanted next.

At the moment I was reading Ultraviolet, by RJ Anderson. It was one of my favorites, about a girl locked up in a mental institute because nobody understands what's wrong with her. In the end, it turns out that she has Synesthesia. Then there's the added mystery of her classmate Tori, who goes missing at the same time as Alison has her mental breakdown…

The door to the bathroom opened, startling me out of the book. Marking my page, I raced to the bathroom, pushing past Molly in my haste.

"Hey!" the girl cried.

"Sorry!" I yelled, slamming the door shut and turning the lock.

Twenty minutes later I was descending the spiral stairs into the Ravenclaw common room. Feeling oddly cheery this morning, I waved at the giant statue of Rowena, and trotted out of the door.

Hogwarts is a great castle. There are so many staircases, trapdoors and passageways, you can get anywhere in no time at all! As it was, I was in the Great Hall for breakfast not five minutes later. I waved at Erin, my second-year sister, who was sat at the Hufflepuff table with her friends. Erin waved back, and I took my seat at the Ravenclaw table. It was still early, only twenty-past eight- Mhea wouldn't be here till half past at the earliest.

I was just finishing my mountain of toast when Mhea came in. I looked up, and my face fell. She was still hanging around with that Logan Bradley guy. Now, I'm not one to judge or anything, but I really can't stand Logan Bradley. He's Slytherin, like Mhea, but in the year above us. He's tall and dark-haired, a muggle-born, and super-popular. He has his own little gang that follow him around, mostly Slytherins, a couple Ravenclaws and even a Gryffindor! Now that was something you did not see every day.

Deciding that I was done with breakfast, I picked my bag up from the bench beside me and wandered over to the Slytherin table.

"Hey Mhea!" I greeted. Mhea turned to me, grinning.

"Hi Abbie! Hold on a minute-" She turned to say something to Logan Bradley (at whom I glared), before picking up a piece of toast and following me out of the hall. Now, up until fourth year, Mhea never ate breakfast. These past couple years I've managed to convince her to eat something, but she never takes much. That's why she's so easy to lure away from breakfast...

"Care of Magical Creatures first," I told Mhea. "Then Defense."

"Speaking of Defense," Mhea fumbled with her bag, "Did you do that essay on the patronus that Professor Jameson asked us to do? It's supposed to be six inches, but I only got four…"

"Want to copy?" I sighed, holding out my six-inch long essay. Mhea nodded, taking it from me.

"Thanks!" she grinned, scribbling stuff down.

"What do you think Professor Hagrid has for us today?" Mhea asked me, handing me back my essay. I slipped it into my bag.

"Knowing him? Probably a manticore," I sighed. Mhea nodded seriously, then we both cracked up.

"Come on!" I gasped, "Let's go down to Hagrid's!"

It only took five minutes, and fifteen minutes after we left the great hall, class had begun.

"Today class," Professor Hagrid said, "I got a treat for yer." The class exchanged an uneasy glance. Hagrid's treats weren't always, well, treats, if you know what I mean.

"Today we'll be goin' in ter the forest. There's a couple o' unicorn foals I want yer to meet."

Mhea and I exchanged an excited glance.

"Unicorns!" I hissed.

"Unicorns are epic!" she agreed. Whispering amongst themselves, the whole class followed Hagrid into the forest.

A/N: I will post 2 chapters (an Abbie and a Mhea) at a time, since a lot of these chapters are short. Also, if you hadn't guessed, Abbie, Mhea and Erin are real people. Abbie is me, Mhea is my friend and Erin is my little sister.
