SOLVED. Science fiction/thriller about a young man and woman who were cloned from two scientists but grew up not knowing anything about it. [s]

[Mandy]

I read this book about ten or fifteen years ago but can't for the life of me remember the title or the author. I do remember that it was a hardback and it had a lenticular cover of a mans face that when you angled it it became another mans face. It was a green book.
The plot was a man and woman who were cloned from two scientists but grew up not knowing anything about it. Then when the male scientist was old and sick he arranged a car crash (I think) for the man so he could transplant his brain into him. The transplant was a success or so he thought. The young mans mind was still in there and fights to regain control. It was a sad story because the young man was so in love with a girl and he wasn't ready to leave her. This is all I can remember and I can't even remember how it ended but I really want to buy it again. I'll recognise the book as soon as I see it, I just can't remember the title or author. Any help will be most grateful received. It's driving me bonkers.

Thank you so much

Mandy--the app definitely leaves a lot to be desired. But the owner of GR has always refused to do anything about it, so we have to suffer with it. Not being able to do everything in the app, especially if you travel a lot, and have to use a tablet or phone means that it's almost impossible to do anything--no links, no editing, hard to sort through all the messages. . . .
