Christianna Thomas' life was boring. When her sister Alexandra convinces her that it's time to live a little, she embarks on a night out but manages to retain no memory of the event.

She contents herself, however, with her new career as a writer - something she's always wanted. During an event held for her father, she comes face to face with a man she thought she'd only seen in her dreams.

Nicholas Prescotti, too, has been haunted by that night and this woman he's only seen in flashes he doesn't believe are real. It took one moment for Nicholas to see Christianna for the memories of that mysterious night to come flooding back.

As they find in each other something they never could have anticipated, their lives are overshadowed by the danger that threatens them both.

When Christianna learns of the truths and dangers, will she leave Nicholas or will she discover that she can't walk away?
