Countdown to Zero Hour (Black Ops: Automatik #1)
Nico Rosso

Chef Hayley Baskov knows better than to get involved with someone with such close mafia ties, but the handsome bodyguard who brought her to this cold, sprawling estate full of ruthless mobsters is inexplicably kind. A little firtation may keep her safe amidst the growing menace.
As Art’s timetable for action escalates, so do his encounters with Hayley. Stealing what illicit pleasure they can keeps them both sane in the face of evil. But when things get dangerous, Art has to tell her about his assignment, bringing her deeper into the shadowy world of black ops...and putting her life on the line.
Now Art has a new objective: protect Hayley from the man they both call boss.
