Gun metal heart
(Book)

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. At the same time, a small group of disgraced CIA agents have been waiting for their chance to exact revenge on Daria. When they learn she's in contact with Diego, they get the okay from their former bosses to take her out. With several highly trained teams out to get her, a partner withholding critical information, and a missing invention around which everything turns, Daria is in the worst danger of her life. And she couldn't be having more fun.
