First recruited then rejected by the CIA, Erika Rivoli has moved to Turin, Italy in 1977 to lick her wounds in the land of her ancestors. There, in the dead of winter, she is catapulted into a spy's life through a budding love interest, a Red Brigades terrorist plot and a secret personal tragedy which threatens to upend her life as she knows it.
Blinding fog, rain, and snow are the least of Erika's obstacles. A more perilous enemy is her entanglement with opposing communist and fascist terrorist gangs shooting up Italy in this epoch known as the Years of Lead. With few allies and many adversaries, Erika navigates a world of danger and mystery, from bombings to Turin's ancient occult, only to discover that people, including herself, aren't who they seem to be.
