It was after they got their cutie marks, that the Cutie Mark Crusaders get the chance to go to Canterlot with their families and celebrate Hearth's Warming Eve. A time full of fun moments, chatting with friends, and many more activities. For Luna however, it is a reminder of all of those positive plus one negative she will be the only one to remember.
The Cutie Mark Crusaders ever so curious, follow her through the whole castle avoiding a few obstacles along the way but what they discover will forever change their understanding of what Hearth's Warming truly means to the Night Princess.
EDIT: Link to a contest thread right here! Holiday Spirit Contest This isn't really important, but it's one of the rules for the contest at hand, so I had to obliged 
*Looks at chapter title.* Just by looking at the chapter title, I already know what Luna's so depressed about.
6611009 A little too spoilerific?
6611637 Depends on who reads the story.
6611646 Conveniently I thought of a better title that wasn't to spoilerific yet has a nice tone with it
6611734 *Thinks for a bit.* Yeah, it DOES have a nice tone to it. And it's not too spoilerific.
6611751 Hehe! Well considering there are actual flowers named that, it makes sense
Great story! I have to admit that I almost cried at the CMC's encounter with Snowdrop.
Anyways, don't forget to link the contest thread in the description; it's one of the requirements. Since you were the first one to submit your entry, I've already judged it. Just have to wait for the rest of them now.
6611883 If the rest come that is
Sure, I'll put the contest thread on the description since you noted that. I actually shed a few bits of tears of my own while I was typing this, who knew I can make myself cry while writing this?

No one knows.
Liquid pride.
You win.
6624503 Why thank you good sir
You're not the only one to shed some liquid pride, I shed some while I was writing this story 
Wow... This story is just beautiful.
6695313 Thank you sir, at least in this contest, there's competition so yay!
Ahhhhhhhhhahahahahahahahhhhhhhhhhhg! The Feels!!
6835993 This is my reaction to your comment...
Because I find it so funny! But thank you nonetheless for reading the book!
Most of this story is good, but I find issue with the way Nyx was suddenly introduced. Don't forget, most people wouldn't know that name on sight, I understand she's a popular OC and everything, but an OC is still an OC. To a casual viewer, Nyx just comes out of nowhere, that's not to say your story is bad, but it might confuse some people.
All in all, 8/10.
6852039 Yeah that was understandable, originally she was actually supposed to be a major part of this story alongside the other three, but for reasons unknown, I had to scrap that... I may end up editing this story to either add truly or keep her out
6852133 Bravo made me loose my liquid Pride
beautiful just beautiful
