Mood Wings - Observations on Pegasus Body Language.

When Twilight Sparkle finds this book, she discovers an entirely new field of research. The secrets of pegasus wings lie before her, and she insists on making her own observations on the matter.

How?

Field research, of course.

Twilight Sparkle is a gifted student and scholar. When she attempts to harness her creative side by writing a science-themed sensual romance novel, however, things rapidly get out of hoof. Can her friends stage an intervention before she humiliates herself (and them) at a prestigious literature recital?

No. No, they cannot.

Sometimes, bad things happen to good ponies. A year following a tragic incident, Twilight Sparkle returns to Ponyville to visit what she has been missing - her town, her memories, and most importantly, her friends. But will everything be as she remembers it?

This story has a sequel titled "In History, Maybe".
