In From the Cold-What Is Burning?"

 Newly divorced mother Jenny Franklin arrives in Madrid as a chaperone for her daughter Becca's figure skating team. After she leaves the hotel on an errand, Jenny is abducted by CIA agents led by Chauncey, who claims that she is the legendary Soviet-era spy, the Whisperer. When she denies it, Chauncey orders her to be killed and Jenny is forced to reveal herself by using advanced combat skills to try and escape. She is offered a deal by Chauncey: assist the CIA in tracking down the source of a series of bizarre incidents in Madrid, or spend her life in prison and have Becca's life ruined. She agrees and is tasked with obtaining a retinal scan of an inmate in a restricted military prison, where she is chased by violent male inmates. With no other choice, Jenny undergoes a painful physical transformation that enables her to assume the identity of a man.

In 1994, a younger Jenny, then going by her real name of Anya, is assigned by Russian intelligence to kidnap the daughter of a bioweapons engineer attempting to defect to China.
