Days before their wedding, during their last separate nights of hard-partying singledom, Emma Holden's fiance goes missing. Not only has Dan disappeared without a trace, his brother has been found beaten and left for dead, and may not wake up from a coma. Without any evidence, suspicion for the attempted murder falls on the absent Dan - but Emma refuses to believe he is guilty. Then crime scene photos are splashed across the pages of the London tabloids, and Emma knows that someone is following her. Watching her. It is an old, familiar feeling, though no less terrifying. As time runs out, her trust in her family, her friends - and Dan - faces an ultimate test.
