CosimaDelphine by ralst31
Sarah is an outsider and orphan whose life changes dramatically after witnessing the suicide of a woman who looks just like her. Sarah assumes her identity, her boyfriend and her bank account. But instead of solving her problems, the street smart chameleon is thrust headlong into a kaleidoscopic mystery. She makes the dizzying discovery that she and the dead woman are clones... but are they the only ones? Sarah quickly finds herself caught in the middle of a deadly conspiracy and must race to find answers about who she is and how many others there are just like her.
This show is so good that I'd be recommending it even if it didn't include one of the cutest, but complicated, examples of geek-love on the planet. The lead actress gives such convincing performances as all the clones, that you actually have to remind yourself that they're not, in fact, played by different actresses. Cosima is an absolute delight but I also dare anyone not to fall in love with soccer-mom Alison, who really comes into her own in the latter part of the season.
A second season has already been commissioned, so it's safe to immerse yourself in this show, because you already know there's going to be more.
Now bring on the femslash!
