Hello!
I don't know if this is the right medium to search for them but I've been looking everywhere and cannot find them. They're from the same author, like a saga.
It includes all four sisters, the couples are Piper/Leo, Phoebe/Coop and Paige/Henry. Prue also gets pregnant from ghost Andy and they have half ghost half witch triplets or twins. I know Phoebe's middle daughter has pyrokinesis and when she first visited the past along with her sisters and cousins she was afraid Phoebe would of thought she wasn't Coop's daughter. I remember Paige twins Pandora and Phoenix(?), I think one of them got a tattoo and Henry was upset because of it. I also remember Melinda's power was cryokinesis. And also Phoebe's youngest daughter had the power of resurrection and it was taken away from her. There was a follo up story of the grandchildren and everything, but I can't remember a single name. Perhaps they are deleted.
Anyhow, thanks! ...
