The Boss by Melissa Schroeder

Sick of the spy game, former CIA operative Vic Walker takes time off from his security firm to figure out just what he wants out of life. But peace and quiet isn’t in the cards with a former business partner and ex-lover like MacKenzie Donovan.

Mac doesn’t like asking for help from anyone, but this latest case has her in a little over her head. She crashes back into Vic’s life with the CIA, the Russian Mob, and the FBI, on her tail after a job goes south.

But even as old feelings rise to the surface while they’re busy dodging bullets, the authorities, and mobsters, they’ll need to get out alive before they can have a second chance at love.
