Nowhere to turn 

When she witnesses her boss's murder, Chelsea Rogers is forced on the run. Hiding out as a personal assistant to a wealthy matron on a Hawaiian vacation, she hopes to stay off-the-radar. But then Alex Sullivan, her employer's dashing but highly suspicious attorney, starts digging into her identity—and hired guns begin stalking her every move. Another murder leaves her with no choice—she has to trust Alex to have any chance of surviving. But when the threats against her put them both at risk, will the danger she can't outrun cost her the man she's learned to love?
