This is frustrating me because I'm pretty sure I only read it a couple of months ago. And it's very possible that I found the link in this forum in the first place (though I've gone through the topics with relevant subject names and found nothing.)
Anyway, I remember quite a lot about this one so hopefully someone will know what it is.
Buffy's pregnant by Angel, they're driving somewhere. They stop at a shopping centre and Angel drives off and leaves her there. Buffy ends up living in the shop. I think Joyce gives her a plant, and to try and keep it alive she goes to the library, where she meets Spike. I think Dru was there--his sister?
She meets the rest of the gang and becomes friends with them, but doesn't tell them about where she is living. I think she goes into labour one night in the locked shopping centre and Spike, who was outside, has to help.
Ring any bells with anyone? Thanks! |
