Carrie Richards is a psychic and also a kindergarten teacher. She sees Dean Sheffield's Doppelganger 3 times before meeting the living man, and begins to understand his life is in danger when they do meet in the flesh. Dean, meanwhile, has had 3 near-fatal accidents in 2 weeks, and through the course of the first half of the book, comes to believe these are really murder attempts by a member of his family.
Carrie and Dean work together to try and solve the mystery of who is trying to kill him, while in the meanwhile the stakes rise as there is a further attempt on both their lives, and Dean's housekeeper is killed.
The story is more about solving the mystery of who is behind the murder attempts, almost incidentally combined with the developing romance between the 2 central characters, as the more rational Dean struggles to accept Carries gift.
The Doppelganger effect did not happen again after Dean and Carrie actually met - I believe this to be an oversight by Tun, as there were further attempts on Dean's life after this point. That it is not used again makes it seem more of a literary device / hook than a true basis for the tale.
This asside, the story develops at a good pace and there are plenty of secondary characters whose story the reader can become involved in - if not Dean's family, then Carrie's.
I was a little disappointed at the rather unsurprising romance development - no real chemistry or heat, I thought, which is the reason for me giving the story only 3 stars. But if you like a murder mystery, this book will deliver.
