She swore never to trust a machine. He was never meant to fall in love.

Chicago, 2056. When her husband vanishes without a trace, young housemaid Marci will do anything to protect her two young sons.

On the other side of the world, Jack, a two-meter-tall combat robot who should feel nothing, breaks his programming to desert the killing fields… and to honor a dying soldier’s last wish: find and protect Marci and her children.

At first glance, Jack and Marci have little in common. But both are linked by an unscrupulous enemy with a deadly secret. To save themselves and humanity from ruin, they must work side by side on a dangerous mission.

A steamy, dystopian sci-fi romance, 'Operation Iron Heart' is ideal for fans of Ruby Dixon and Teyla Branton.

Martina André is the author of "Rebel Hearts", a sexy, fast-paced sci-fi romance trilogy that explores love across the human–machine divide.
