Nightfire (Protectors #3)

Chloe Mason's childhood memories consist of seemingly endless hospital stays. Now all grown up and healthy, her determination to fill the gaping holes in her past leads her to her long-lost brother, Harry . . . which brings Harry's friend and business partner, Mike Keillor, crashing into her life and her heart.

Former Marine Force Recon sniper and SWAT officer--a martial arts expert and owner of a successful security company--Mike can deal coolly and efficiently with any threat . . . until he's blindsided by something he never expected: fierce, fiery passion . . . and love.

But when Chloe inadvertently crosses the Russian mob, Mike realizes that evil is darkening his world once again. He has already lost his family; he will not lose the woman who enflames him, who makes him whole. Failure is not an option.
