An invasion threatens human civilization and to help stop it Ianto is forced to reveal who–and what–he is.
Why You Should Read This:
This is an elegant story, one of sarcasticchick’s very best. Most of it is from Ianto’s POV, which is really effective, because from the beginning you get the feeling that there is something very strange about our Mr. Jones.
The other thing I like is Jack’s reaction: horrible grief, suspicion, confusion, anger, despair, and just enough hope to get by.
I totally adore this fic. However the link provided above no longer works. The fic can still be read on AO3 via this link: http://archiveofourown.org/works/309415
