Query: Too tenuous and vague

A bit too much of a mixed bag for my tastes. We are supposed to believe he has supernatural powers, we are supposed to think he is a ghost. Then he is an amnesia victim, but somehow he recalls all sorts of things about his past life. She is supposed to be a Private Eye sent by his sister. The motives of all the villains are not threshed out clearly, and the book just has too many inconsistencies. The characters also lack depth-I mean, this is Harlequin but they should still be something other than their jobs or medical conditions-we never do get to find out why they fall in love so intently in the first place seven years ago, let alone now. And the fact that they already love each other diminishes the tension. Since we don't believe in the villains or the insuperable obstacles, we don't believe in their love and commitment either.
