• Cosima is the cosmic geek and PhD student in Experimental Evolutionary Development Biology who helps her clone sisters make sense of the science behind their existence. After getting embroiled in a steamy and sometimes dangerous love affair with the enemy — Dyad scientist, Dr. Delphine Cormier — Cosima’s life is even more complicated. She has a congenital respiratory illness unique to the Leda clones and is obsessively driven to get to the truth of their biology. Cosima hopes to free them from their collective (and fatal) destiny through newly discovered research, but will she be strong enough to continue the fight to save them and ultimately herself?
