Angelus vamps Buffy, Spike claims Buffy, Dalton bemomes their Childe

Angelus vamps Buffy ... Buffy wants revenge, Spike and Buffy fall in love and claim each other.
Dalton who is loyal to spike witnesses the claim..... Buffy then claims Dalton as their childe..
somehow Buffy gets away from the mansion probably with the help of Spike no he is still in the wheelchair I think must be Dalton. Revenge is planned and Angelus is killed and I think so is Xander but its not Xander sorry if ive confued you but im confused

Found it ......revenge for love by Tasha was going through all the found fic and came across it...
Missed it last time I checked

There is a sequel as well - Living For Love but there was only ten chapters done as far as I can remember. It's still a good read though.
