Race Against Time — Lynn Turner

When Samantha Cook wakes up in Washington, D.C. in a strange bed, a strange time, and with F.B.I. Agent Joseph Mercer breathing down her neck, she hasn't a clue as to what's going on. Little does she know that back in her own time and place, Valerie Herrick is in the same predicament. And Samantha's significant other, newsman Lucas Davenport, isn't going to stop asking questions until he finds the woman he loves. But it won't be easy. Samantha and Valerie are caught in a whirlwind of time and destiny. They've switched places--and unless they can solve each other's problems, they're stuck. Can Valerie and Samantha save the world? Will love or the law of physics triumph?
