Therese Sorenson is dead. Before that, she created a genetic retrovirus that can rewrite living DNA, and smart enough to know that in the wrong hands, her retrovirus could be used as a deadly weapon. Rather than let her ex-employer get the retrovirus, Therese and her cloned assistants took their own lives by blowing up their lab. But even that might not have done the trick, since Therese left behind an errant android containing a prototype of the retrovirus. Now it's up to her only surviving clones -- Queenie of the Heartbreakers and former lab assistant Vector -- to carry on their dead boss' mission by keeping the retrovirus away from her old employers. The Heartbreakers earlier made 9 appearances in Dark Horse Presents.
