She walked away from the life. Now the life needs her back. Sixteen years ago, CIA agent Madison Sinclair left the field after a mission went fatally wrong. She chose safety: a desk job, a husband, a home in the suburbs. But you can't bury the thrill forever. Or the instincts that never really left. Madison is asked to step into the breach one more time when a dangerous cyberweapon is offered to the highest bidder. NullEcho can break any encryption without a trace, leaving financial systems, critical infrastructure, and even weapon systems vulnerable. Such a device could change the world forever. And the Russian hackers who developed it already have a buyer. Prince Zaydan Al-Kharabat, is the playboy scion of an oil-rich monarchy that funds terror networks all around the world. He's a dangerous man with unique, dark tastes—tastes that Madison Sinclair is uniquely qualified to exploit. She knows his world, and she knows how to push the buttons of men like him. To stop the sale, Madison must step back into the shadows and enter a world of power, desire, and deception she thought she'd left behind. But can she become that woman again and hold onto everything she holds dear? And this time, the mission isn't just her life on the line. It's the world. The clock is ticking. The price is everything. And Madison Sinclair is about to find out what's left of the spy beneath the soccer mom. Undercover Wife: NullEcho is the new erotic thriller from bestselling author Kirsten McCurran, The Queen of Sexy Suburban Secrets.
