Okay, before we get on to the actual story description, I'd like to give you a fair warning. This story will be the first fanfiction I have written. Not first on this site, but the first ever. So, I'd like to apologize if this story has any spelling/grammatical errors or in general bad writing. Ok, now that that's out of the way, to the actual story description!
Pinkie Pie was, for the most part, a normal pony. Her life had been like a party; funny and great. However, when her and the Mane 6 has a sleepover, something triggers some bad memories. Memories that would reveal shocking secrets from her family and it will be worse than her worst nightmares
EDIT: A/U tag to say that Pinkie is older than Marble and Limestone Pie
