Celestia and Luna were born as unassuming foals in troubled times. But already marked for greatness, the simple earth ponies stand to face a world set against them, full of danger, fear, and sadness. A world they will change forever.

A sweeping epic taking place before Equestria was made, where Celestia and Luna must rise from normal foals to become the Princesses we know them as, beset from all sides by monsters, other ponies, and even the forces that govern nature. Their tale is as tragic as it is triumphant.

At first, Chrysalis loathed him; the dumb-as-a-brick woodspony who goes by the name of Evergreen. But through circumstance, he is her only savior. And slowly, she comes to love the simple pony and his way of life. But her life as a changeling keeps holding her back. Will there be a happily ever after for them? Or are they doomed for failure?

Octavia is a high-class pony. Fine alcohol is her wont, and uncouthness her intense chagrin. Such is her surprise to find herself lumbered with an insufferable oaf of a DJ pony. However, sometimes these situations work themselves into a satisfactory ultimatum all the same.

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

When a mishap occurs with Celestia's bathroom scale, an ancient protocol that may just doom Equestria is set into motion. With the entire palace staff now conspiring against her, the sun goddess must not only contend mountains of paper work, dancing celery sticks, and steroid pumped stallions, but a sister who will take this chance to torture Celestia any way she can as payback for her banishment. Lock the cupboards and barricade the fridge! It's the Royal Diet!

Rarity and Fluttershy have been friends for years, and every week they go to the spa. But after every trip, Rarity finds herself growing greener with envy over Fluttershy's beauty and grace, if not something more than just envy— and what might happen if she finds out Fluttershy feels the same way about her?

(Now with a Spanish translation by the generous SPANIARD KIWI!)

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

A Soot-Covered World, book 1.

When Octavia and Vinyl Scratch decide to combine their respective musical styles into a new genre that will celebrate not only their talent, but also their unique bond, they feel confident that they're the pioneers of the new age. So when the two find their music challenged by another pair of musicians, they set out to make sure that theirs is the best. However, the rival two aren't bad artists themselves, not to mention they’re certainly not… of the same persuasion as Vinyl and Tavi. In the snow-wrapped streets of Manehattan, can they risk exposing their new found -and still taboo- relationship, or will they be doomed to second place?
