Possession Protocol (Protocol #4)
Dawn Ryder

Seneca should have forgotten Beck. In fact, she made it a priority to get past the special ops sniper, but her heart isn’t listening. She isn’t prepared for the moment he walks back into her life just as abruptly as he left it—or the lust she feels for his partner, Marshall Satuik. Beck’s still everything she can’t resist, and Marshall is a temptation she can’t ignore. But hopping into bed with them scares her. What if they disappear again?
Men like Beck and Marshall don’t live their lives in the open. They melt back into the shadows without a trace. But Seneca’s in trouble and Beck never takes any threat lightly. They’re not budging until the threat is neutralized. Which means Seneca has to face up to her desire for both men or risk losing it all…
