It had at least two books, and three clones, the (third?) of which was "The Evil Twin" of the eponymous book / sequel. Could've been "The Evil Clone".
The mother of the first-seen clone gave up her eggs, was a surrogate, or something and that's how she gave birth to Clone 1.
Not sure where Clones 2 and 3 came from, but they end up living in the same town, and the "evil" one is evil because she's been committing crimes and the Clone 1 is being blamed for it.
It is not Marilyn Kaye's Replica series of 27 books, because that's why I want to find this other Teenage Girl Clone series.
I don't think the clones I'm looking for have superpowers? And it's not got any other sci-fi tech around. Just the clones being clones?
