I finished Luck Is No Lady feeling no more attached to the characters than when I started. Without truly being in Emma or Roderick's world, occasionally their actions didn't jive with their character. Like when Emma decides sleeping with Roderick was wrong and "breaks up" with him. In some cases, what happened felt like the author forcing it to happen rather than a natural choice for the characters to make. After her father putting the family into the debt situation in the first place by gambling, it doesn't seem AT ALL in character for levelheaded and sensible Emma to gamble her way to get out of debt. Not without serious angst about her decision. (Which there was little.)
Outside of that, Luck Is No Lady is a decent historical romance for those who like getting outside the glittering ballrooms of London. With her father's debts hanging over her head, Emma decides the only way she can get the money to pay the moneylender hounding her is by working... at a gaming hell.
Roderick is a bastard (by birth, not character) who's pulled himself up and created a world for himself to exist in. While the ton may turn their noses up at him for his birth, they certainly come flooding to his club (and, occasionally, call upon him to give them investment advice).
Emma and Roderick keep running into each other in different places, and neither can really fight their attraction, even though they both try. (For the most part.) I always enjoy the "I want you even though I shouldn't but I want you so bad" plot lines, especially for all the forbidden moments. Curious to see who the couple is in the next book in this series...
