The book

"We need to see Principal Celestia and Luna!" Twight said in a panic.

"Yeah we need to figure out how to stop this and we need to do it now!" Said Rainbow Dash.

"SAVE APPLEJACK ON 3?!" Yelled Pinkie.

"No. We are not doing that!" Said Twilight.

"Now let's go!" Said Rarity.

The girls ran down every hallway to make it to the office. Till they hear a scream.

"THATS WHAT YALL GET FUR GETTIN' MAH WAY!" They hear a girl scream.

"But did you have to throw a glass bottle at my head?" The girl cried.

"OF COURSE AH DID! NOW GET OUT MAH WAY!" She yelled.

"Yeah let's end this." Said Pinkie.

"For once I agree with pinkie!" Said Rarity.

"Hey!" Said pinkie sounding offended.

"No time for this guys! We need to get to the office!" Said Rainbow.

After more running the girls finally arrived at the office and went inside.

"Principal Celestial! We have a major problem!" Said Twilight.

The girls walk into her office and see Luna there pacing.

"Whatever is wrong girls?" Said Celestia.

"Its Applejack!"

At this Vice Principal Luna stopped.

"Applejack?" She asked.

"Yes, or may we sa-"

"Applejerk!" Said pinkie.

"Pinkie! I wanted to say it!" Whinned Rarity.

"Oops!" She said blushing.

"Anyway! Applejack read some kind of book an-"

"Book?" Asked Luna worry growing in her voice.

"Yeah, she wasnt acting like this last night. But we did go to the castle of the 2 sisters. And she did fall into a hole." Said Twilight freaking out.

"A hole?!?" Asked both sisters.

"Yeah why?" Pinkie asked.

"My dear children, my past has come to haunt me. I used a book call The Curse Book, and it turned me evil. When ever someone reads it, Applejack in this case. They will turn evil with every page they read." Said Luna.

Everyone was silent until they heard a scream in the hallway.

Everyone ran out and found applejack standing over Bon Bon with a foot on her chest.

"Next time ah tell y'all tah do something', DO IT!" Applejack screamed.

"Y-yes A-applejack." Said Bon Bon in fear.

"Good!" Said Applejack then she walked away.

"APPLEJACK!" Shouted Rainbow dash.

Applejack turned around and when everyone saw her face, they were feared for their friend. Her face was a lighter tan, with dark circles under her eyes, while one eye was purple, the other one was red. And she had a scar that went over one eye.

The girls gasped at their friends aprence.

"What do yall losers want?" She asked.

"Applejack stop this! This isn't you!" Rarity said.

"Oh Rarity, this is me. Y'all should know that better than anyone!" She said smirking.

"No its not, you've become Applejerk not Applejack!" Said Pinkie.

"You foolish gals. This is all yalls fault, you see Applejack was sick and tired of bein' taken for granted, so she read the book. And ah'm here to change her life for the better!" Applejack laughed.

Everyone by now had faces full of worry and sadness. They lost Applejack, but maybe someone, or somepony can save her. They all hoped.

"But..but...Aj, we never took yo-" rainbow was cut off by a punch in the face by Applejack.

"Oh no, no, no! Y'all have! For example Twilight, when you gave me that book on organized Orchards, you took me fur granted. Rarity, y'all always make me an olfit, but guess what y'all never thank me when ah let y'all do the size stuff!" Said Applejack while almost in tears.

"A-applejack, w-were s-so s-sorry! We didn't know." Said Fluttershy.

"Ha! Please, a couple 'sorrys' are not gunna fix anything'! Now if y'all excuse meh, ah have tah go tah class." She said walking away.

"Is it me or did everyone notice that her voice is deeper than usual?" Asked Pinkie.

In response everyone just face palmed. The girls have to come up with a plan and fast. Because if she reads another page, she'll be in a world of doom.
