I got Never Kiss a Rake as this month's free Samsung kindle book. It was an ok read but nothing special. 
 The main characters seemed more in lust than in love. I feel Byrony would have fallen in "love" with the first good looking man to pay her attention, the way the Earl did. He was just the first one she had contact with. As for him, he probably just couldn't resist a young pretty girl in his household all the time. In addition, it was odd that despite being married for ten years, as well as sleeping around, his wife never got pregnant (in a time of no reliable contraception). It seems unrealistic, unless she couldn't have kids, but there was no mention of that.
