The book title, pic, and description made you think that the hero and heroine we going to have a fake wedding and that was the reason I decided to read the book. However it's not like that. I'm trying not to give too much away for those who plan to still read it.
The chemistry between the hero (Allen) and the heroine (Belle) is not quite believable to me because they meet on the day they are going to use this publicity stunt to improve his image and next thing you know they are seriously in love with one another. I believe in instant attraction but the hero and heroine are not allowed enough time to have truly fallen in love with one another.
I think that if the author had added more details to the idea of the fake wedding it would have made the chemistry between the hero and heroine more believable.
