Author's Summary: When Nyssa tries to return home with the cure to a deadly plague, the TARDIS overshoots and slips back into her past, the Doctor's future. Worse, the Master is already there, taking a sinister interest in her family. Hemmed in by potential time paradoxes, there's only one person to whom Nyssa can turn for help: her best friend Tegan.
Characters/Pairings: Nyssa, Other Character(s), Tegan Jovanka, The Doctor (5th), The Master (Ainley), Turlough
Recced because: This fic is based on the Big Finish arc where an older Nyssa joins Five, Tegan and Turlough for a spell in the TARDIS, but this can be read without any knowledge of the Big Finish audios. What I love about this fic is that it feels like a Big Finish audio or even an old serial with Five in it. There's action, witty quips and a paradox that needs to be fixed or else. I highly recommend this for Classic Who fans.
