"Alright what even is this? Why hasn't this been featured, and why are there so few upvotes? I almost passed it by and I expected to drop it immediately due to low quality. But, nope it’s the best human raised by equestrians I’ve read this far." -A Predatorial Horse

"This was a fantastic read that I just happened to come across randomly.
This is a unique approach that is a breath of fresh air. In a sea of mostly silly stories, you're creating something that seems more real than most. Thank you for your work on this take, and I will be looking forward to seeing this story through!" -Chillean

"GREAT STORY!
It's rare for me to come across a good human in Equestria story that feels organic and not forced.
Too bad it's over. Now I've gotta wait years for the sequel to be done before I can read it." -Mocha Star

"Upside to reading at work: quality entertainment while waiting for the day to end.
Downside to reading at work: when said quality entertainment legitimately makes me cry in empathy." -Striving for Harmony

A non-spoiler review to whet your appetite!

For Celestia, life had rarely been better than it was now. Her sister had been returned to her, Discord was freed and subsequently defeated in record time, much to her private amusement, and her niece and her coltfriend had ideas of marriage in the not too distant future.

An event that would no doubt be yet another historical day in the rapid series as of late.

Yet, history is made even earlier than expected as Princess Celestia finds a strange letter in her room one night. Someone claiming to be the prince of an unheard of species is asking for Equestria's help. Making the dire situation described in the letter even more urgent is the warning it held.

Celestia and her fellow princesses are eager to meet the strange colt who has revealed his own mother's invasion plan of their kingdom to them in a bid to gain trust. Of all the ponies to meet this strange colt, however, it's one Raven Inkwell who will find her life turned the most upside down.

And by the end, she wouldn't have had it any other way as she comes to know Prince Anonymous of the Changelings.

This is an RGRE story starring (what should be) everyone's favorite mare, Raven Inkwell and a friendly changeling prince as they work to navigate politics and establish peace between two kingdoms.
