The heroine is supposed to be dyslexic, but the author does such a poor job, she ends up to my mind just being stupid. I have dyslexia (although far milder a case than my mother and sister) and I found myself completely confused by the author's description of dyslexic problems. They would start fine, but degenerate into stupidity because there were none of the strengths that often give dyslexics the ability to cope with information and getting places even if they never learn to read or tell their left from right. I could literally not name a single admirable or endearing quality in the heroine other than beauty. The only sympathy I had was rooting for the underdog.
The hero was no better. Misunderstanding and a false sense of betrayal are staples of many romances, but this "hero" was nastier than most and persisted in his nastiness long after he knew his bride was actually innocent. I could not muster a shred of sympathy for him and by the end of the book I just hoped that the heroine would leave him and find someone worthier of her.
