Seduced By Three — Sylvia Ryan

Grace Hunter is trained in survival and doesn't need anyone to protect her from the anarchy that results after the EMP. But still, she is stuck confined in an underground shelter with three men-Steven "Sarge" Connelley, Van Goodwin, and Luke Evers-all totally different, all powerfully sexy. Together, the group faces the threats of the deadly city above ground. Individually, each man succeeds in seducing her. And before long, all three want Grace for himself alone. Animosity inside the shelter grows unbearable until Grace finally resolves to end it once and for all...and simply vanishes without a trace. It takes months for the men to eventually realize that Grace left them willingly. When they do, hostilities flare between them again. They fight each other, and then fight together to muddle through the complexities of sex, love, and their own egos to forge an arrangement that could make them all happy.
