Reviews and other word-of-mouth:
"I just can't find words for how much I enjoy the ideas on display here. … I didn't expect to be rating something this highly, this quickly." –Bradel
"The Lotus Eaters was the story that made me realize horizon wasn't just good, he was really good. Then Fugue State showed me he was really good repeatedly." –Bad Horse
"a strange but intriguing story ... [horizon's] so good at this ponyfic lark that it's still a highly satisfying read. ★★★★" - Louder Yay
"This story is weird, and I mean that in a good way. … [Horizon] thought about how ponies might react if [musical numbers] were a constant in Equestrian life." –Chris

Fugue State now has a sequel!

Princess Celestia is a living legend, but much of her life is shrouded in mystery. Records have long since been lost to the decay of time, and the tale of her triumph over Discord has become a fable. The Princess's memory of the event has long since faded... or has it?

Her faithful student lending an eager ear, Celestia recounts the true story of a war-torn Equestria, the struggle against Discord, and the early years of her own life.

Before she was the Princess of the Sun, she was merely a stranger.

This is the story of a very ordinary pony's extraordinary day. Carrot Top and Derpy are good friends indeed, and sometimes friendship can lead to wonderful surprises. It can also lead to arguments, frustration, and general grumpiness, of course, and this story has all of those things as well. But mostly, this is a story about the day Carrot Top learned how to fly.
