Once upon a time, Marcus Bennett was just another misanthropic student struggling to survive college. However, upon the seemingly impossible arrival of an amnesiac and totally helpless Twilight Sparkle at his door, it looked like his life was finally taking a turn for the wonderful and everything was going to be smiles and friendship forever. They could move out to the country and go run through the forest together and-

Yeah, like he has that kind of luck.

Together with the tiny purple unicorn, a yellow military-mare-turned-stuntpony, and a slightly (very) insane girl reporter, Mark is thrown into a world of confusion and conspiracy around an ancient grudge that's suddenly coming back home in the worst way. It'll take everything they can beg, borrow, and steal just to survive in a conflict that may not leave Earth or Equestria standing when the dust settles.
