Query: This is by far the worst book that exists on this planet.

This is by far the worst book that exists on this planet. Heather Graham seems to think being forced into marriage and then being systematically raped by your husband is romantic. Remove the sex/rape scenes and you have an incredibly boring boilerplate story. The civil war backdrop provides the only fleeting element of interest. Not only did I find this book disgusting, I found it's suggestion that marital rape is somehow arousing morally offensive. The only reason to have this book in your possession it to destroy it, which is a public service.
