I know it's been asked for before but I can't see to find it.
An amnesia suffering Buffy is brought back and is immediately drawn to Spike.
They take her to Lorne to sing where he says he doesn't know IF she will ever get it back.
He brings a woman (witch/healer) in to help her but somewhere along the line they are attacked by her sister who is as evil as she s good.
Tara and Dawn have a big part in the battle.
When its over, Buffy and Spike pack everything up and leave when the others are still sleeping I think the only one to notice is Oz but he says nothng and lets them go (That last part might be another story though as it's been a while since read it.)
Sorry it's not more but that is all I can remember. |
