Author's Summary: After settling in Rome in 2004, Buffy started dating a man known only as 'The Immortal', and who was - by all accounts - entirely too good to be true. What if one of his other names was 'Captain Jack Harkness'? This crossover explores how this could be possible, ties the two 'verses together (including all those flashbacks) and shows why Buffy and Jack were perfect for each other at that point in time. Canon compliant in the extreme.
Characters/Pairings: Ianto Jones, Jack Harkness, Other Character(s), Owen Harper, Suzie Costello, Toshiko Sato
Recced because: My main fanfic habit is Buffy / Angel, and My Immortal is simply the best Whoverse / Buffyverse crossover I've read, which somehow combines elements of both canons without ever putting a foot wrong, and does so with style in a beautiful romantic comedy, and without any changes to canon in either fandom (if you ignore the "season 8" Buffy comics). The Immortal is probably the most mysterious figure in the Buffyverse - although he never appears on screen he's the focus of The Girl In Question, one of the funniest episodes of Angel, and Jack Harkness fits the role to perfection. It helps if you know a little about the Buffyverse and its characters, vampire slayers, etc., but it isn't essential. There are two sequels, both much more serious in tone.
