Years after Buffy dies in S5 Spike is in L.A with Angel when he saves a girl who looks just like her

Hi im trying to remember the name of a fic i read a while ago. Spike is in L.A working with Angel i think in this fic Buffy never came back after dying in season 5. But one night he finds a fighing or being attacked and Spike shows up to save her. The girl looks just like Buffy but she doesn't know him or Angel. I think she was "re-born" as a side effect of Willow trying to bring her back or something like that.... can anyone help me out please

That's Remember When by Ashlee I think.

Summary: Set almost seventeen years after The Gift, Spike is now living in L.A. working at Angel Investigations. When he's out on patrol one night, he comes across a girl who is identical to Buffy in every way...except she's a teenager. Spike and the Fang Gang now have to figure out if this girl is the same Buffy Summers who sacrificed herself so many years ago. And if she is- will she get her memories back of a life that she doesn't remember living?

That's it thank you so much

You're welcome
