Twilight revels in her successful vengeance, toying with Dr. Mary Parvotti and the shellshocked Sun Princess Celestia as her civilization-destroying plan continues apace. The two lovers will have to use every trick in the book to keep their souls out of the young alicorn's lusty clutches, but all is not as it seems. One way or another, everything ends here, with the fate of the world hanging in the balance. No pressure.

This is (not quite the) final story in the Mary and Celestia series. For those who've read the whole thing (it's pretty much a novel length at this point), thanks for sticking with me. Look forward to more, both with Dr. Parvotti and elsewhere.
