Somepony is out to get Rarity but the Ponyville police don't believe her so she turns to the only pony she can, Hidden Eye, Private Investigator. What at the surface appears to be a simple burglary ends up with Rarity and Hidden Eye finding themselves wrapped up in something far darker.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.
