Ok I start to read that story on sinister-attraction and lost it because I stupidly pushed wrong button on my HTC now I cant find it

Buffy lost her vision because of some acid spitting moster. It can't be restore by her slayer-health or with magic. She decide to end her life by loosing fight but Spike helps her out. Later he takes her to trails but he is the one who should go through for her to get her vision back. At the end of trails he dies and she safes him with her blood. That happen to be last trail and her wish granted.
Thanks ahead
