While reading this book, especially the first half, all I could think was "Oh yeah, I know this book. Except it was called Rebecca. And Lakecrest was called Manderley and it was way better written than this".
This is a little harsh (though not unfair) because you could reach the moon if you stacked all of the books that have this basis premise on top of each other: poor girl meets rich but mysterious man, whirlwind romance, quick marriage, he brings to his ancesteral home, family is mysterious and unwelcoming and then the mysteries of his sordid past unravel.
As the book went on it came into it's own a little bit more, but noone of it was reinventing the wheel. However it's a pretty short, fast read so if you want a little escapism this isn't the worst way to go. I think it's like, 276 pages?
I read this for my work book club so I will have to think of something more constructive to say for our meeting :)
