To pleasure A Prince

To Pleasure A Prince by Sabrina Jeffries is very close to being a wallbanger for me because the hero in this book is truly hard to tolerate and the heroine's "growing affection" for him comes off like increasing desperation on her part to emulate her martyr-prone romance heroine sisters. On one hand, I try to be patient with this book. I've read bad boy heroes who push the limits of acceptable behavior, enjoy these books, and there's that. But Marcus North isn't a bad boy as much as he comes off like a snarling caricature, the illegitimate son of the Tasmanian Devil and Wild E Coyote, with absolutely no redeeming feature whatsoever where I am concerned to commend him to anyone other than women who write love letters to men on the death row.
Marcus isn't abusive, physically, but his actions are so offensive to me because he acts like a ten-year old boy denied his candies. His actions are completely self-absorbed. In fact, I don't remember encountering any hero as self-absorbed from start to finish like our Viscount Draker here.
Regina Tremaine is our heroine and she has a secret. Maybe I shouldn't reveal the nature of this secret, so I'll just say that she has a valid excuse to hope that Marcus' sister Louisa be the wife to her brother. Marcus believes that her brother has shady reasons to court Louisa, so he opposes the relationship. Being a heroine, Regina naturally confronts Marcus in his place (with a chaperone that she leaves behind in the carriage, of course, because this is the Amanda Quick Law that every romance heroine aspiring for greatness should adhere to). What results is a bargain: she will allow Marcus to court her for a month in return for her brother being allowed to court Louisa.
Oh, Marcus. I don't know where to start. His overprotectiveness of Louisa is both filled with creepy Freudian undertones and cruel. He thinks that nobody will accept him because he is the son of Prinny and a well-known harlot, so he believes therefore that Louisa
