Ingrid Lindgren is a femme fatale in my soon-to-be-complete novel Stardust. She is a bioroid genetically engineered to seduce and manipulate others. The only problem for her creators is that she has feelings too, and when her brother (also engineered) gets murdered, she will stop at nothing to avenge him, even if that means attempting to steal the man Miyako loves and generally interfere with Miyako's plans.
