Sustained only by a temperamental mechanical implant that leaves her with mere weeks of life, she cannot bear the thought of Adrian drowning in guilt over her sacrifice.
Beatrix stages a cruel public breakup, flaunting false infidelity so Adrian will loathe her memory after she passes away. But as her synthetic pulse begins faltering and Adrian's enterprise soars to unprecedented dominance, an unsealed medical file threatens to expose the devastating secret she gave her life to conceal.
