The forth book in the Sinful Suitors series follows Niall Lindsey, the Earl of Margrave, sister to Cassandra whom you might remember from The Study of Seduction, and who we later learned fled the country to avoid being prosecuted after fighting a duel with a man who harmed his sister, subsequently killing the man. Seven years later, Niall is back, pardoned, and trying to move forward with his life, including moving on from Brilliana the woman who he was forced to leave. 
 Brilliana Trevor's heart broke the day she had to say good-bye to Niall. Despite being forced to wed her now-deceased husband, she never stopped loving Niall, but the rumors surrounding why he dueled all those years ago keep her from being able to trust him again. However, when her father is implicated in a counterfeit ring, she and Niall are forced to work together to either prove his innocence or his guilt. While working together their undeniable attraction forces them to confront their feelings for one another. 
 The relationship between Niall and Brilliana was heavily teased to us in The Danger of Desire, and of course Niall's own story was partially revealed in the second book, so I loved that we finally got the full story between the two. A lot happened in their time apart from one another, they both exponentially changed. Seeing them figure out whether they could learn to trust each other, coupled with the heat between them, was what really drove the story for me. I felt like the counterfeit storyline took too much of a backseat to be intriguing. I know that this is a romance first, but I felt like it should have warranted a little more balance between the "mystery" of the counterfeiters and the relationship between Brilliana and Niall. 
 Overall, though, I enjoyed this read as I've enjoyed the others in the series thus far. There's a definite hint about who the next couple will be, and I'm hoping it does go in that direction.
