In Gun Metal Heart by Dana Haynes, Daria Gibron, a freelance operative with a long and deadly history, has been slowly recovering from the injuries sustained from her last case. Hiding out in a town in rural Italy, she has been staying as far off the map as she can—until she’s tracked down by an old colleague. Diego had been a bodyguard in Florence, protecting an engineer and her invention, when they were attacked by a highly trained paramilitary group. Diego alone escaped and the White Scorpions, a Serbian mercenary group known for their indiscriminate violence, are now after him. Well, after him and Daria, now that he’s dragged her into the picture. At the same time, a small group of disgraced CIA agents have been waiting for their chance to exact revenge on the person they blame for their discharge—Daria Gibron.
