In the near-future United States, where advanced technology can create egg or sperm from any person´s cells, celebrities face the alarming potential of meeting biological children they never conceived. Famous singer Trace Thorne is tired of being targeted by the Vault, a black market site devoted to stealing DNA. Sick of paying ransom money for his own cell matter, he hires bio-security guard Ember Ryan to ensure his biological safety. Ember will do anything she can to protect her clients. She knows all the Vault´s tricks - discarded tissues, used straws, lipstick tubes - and has prevented countless DNA thefts. Working for Thorne, her focus becomes split when she begins to fall for him, but she knows she hasn´t let anything slip - love or not, his DNA is safe. But then she and Thorne are confronted by a pregnant woman, Quinn, who claims that Thorne is the father of her baby, and all bets are off. Brilliantly plotted and terrifyingly prescient, Baby X is an unpredictаble and relentless speculative thriller perfect for fans of Blake Crouch and John Marrs.
