Dr Alex Taylor finds herself in a nightmare scenario, but no one believes her, not even the man she loves. Things go from bad to worse as each new disaster unfolds. A great story which keeps you on your toes, fast moving, vivid descriptions (a bit too vivid sometimes) - definitely a thriller. I did work out who it was before the reveal but that didn't spoil the story, perhaps the why did, a little. However Alex was a bit too perfect, a goody two shoes really which was ever so slightly annoying. Be careful if you are reading this on public transport because you might just miss your stop!
