A thriller set in The Conversion Bureau universe

It is a cold new year in Chicago. On her way home, Fiona bumps into a stallion named Chase and decides to help the drunken pony back to the Bureau he is staying in. They soon find themselves dangerously entangled in a chain of events that is bound to teach them a lesson or two of both man- and ponykind. But when the future of Earth as well as Equestria is at stake, learning can sometimes be very, very hard.
