Part of the extended Millerverse!
Donald and Danielle Miller are an odd couple of twins; regardless of their differences, they get along just fine. Mostly.
Things become stranger by the day when a lost girl appears in the middle of the night. Cold, wet, lost and confused, Trixie Lulamoon is found by the fraternal twins.

But her tales of being a pony are hard enough to believe; maybe the girl is just crazy.
At least, they hope so.
