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 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 who claims that Thorne is the father of her baby, and all bets are off.

Claire Abrams' dreams became a nightmare when she passed on a genetic mutation that killed her little boy. Now she wants a second chance to be a mother, and finds it in Robert Nash, a maverick fertility doctor who works under the radar with Jillian Hendricks, a cunning young scientist bent on making her mark. Claire, Robert and Jillian work together to create the world's first baby with three genetic parents --- an unprecedented feat that could eliminate inherited disease. But when word of their illegal experiment leaks to the wrong person, Robert escapes into hiding with the now-pregnant Claire, leaving Jillian to serve out a prison sentence that destroys her future. Ten years later, Jillian will stop at nothing to reunite with the man and daughter who should have been hers.

A fearless doctor must protect a vital secret from the world---even when she falls in love with the man who’s determined to break her.
