Now, back in their parents' private clinic, they are the subjects of one final, desperate experiment. Their mother, driven by scientific hubris and maternal guilt, prepares to neurologically realign them using an untested drug.As the "e;Synergy"e; is forcibly reborn, the twins must navigate a flood of shared agony to survive the threats closing in from both their pasts.
