I completely agree with the reviewer that said there is absolutely no reason to make Simone a vampire. The only purpose it serves is to turn this character into an unpleasant, humorless walking pity party. Night Fires would have worked better as a straigh forward historical for all the impact the vampire gimmick made on the story.
As others have said, this takes place during the choas and terror of the French Revolution. Simone returns to her family estate to find the family that turned their backs on her murdered. She slays the killers, and then runs off to church to beg forgiveness. The priest instructs her to dedicate her life to help other flee from the agents of the revolution. Hence, Simone becomes La Flamme, a Scarlet Pimpernel minus the brains clone, dedicated to rescuing imprisoned aristocrats. At the same time, the English government sends over a spy named ..er... I'm drawing a blank... let me check... (I just finished the book an hour ago) yes... Micheal Corday to seek out and assasinate the one financing a revolutionary movement in England.
As a historical spy romance, the book is also a dud. Simone is again the problem. For someone who risks danger at every turn, she sure is stupid and ineffective as a spy. I can't see why a seasoned expert like Corday is so adament that he must enlist the help of La Flamme when he isn't sure can trust a third party and Simone is more of a help than a hinderance. In fact, if Corday just went to Paris without her, the book would have been finished in a third of the time and we'd all be spared Simone's endless self-flagellation. She's cursed, she's evil, she's wicked, she must suffer, she must wear a hairsuit, and she must give us every detail of her pain and agony because we must suffer along with her.
But honestly, in particularly silly scene Simone is vowing to herself not to sleep with Corday and reveal her true name and other information. Not three pages later, Simone has succomed to his charms and answers every one of his questions, spilling all her secrets as they do it! A few pages later, the government spy keeping an eye on them mentions how inept women are at keeping secrets. I laughed. I sure hope the author meant for the irony to be there. There is also a another part were Corday wants Simone to pretend to be his wife, but she can't because lying is bad and marriage is scacred or some other nonsense. She nearly gives them both away in front of hostile French agents! Simone, even though her life's misson is to decieve and ellude the revolution's agents, isn't even flexiable enough to act outside the Moral Code of Virtuous Romance Historical Womyn That Make Them Pure and Likeable to Ye Puritanical Readers to save her own life!
In the end, they finally make it to Paris and do what they need to and everything is hunky dory even though the plot elements just come together out of Serendipity rather than actual spy work. Corday and Simone live happily ever after. The End.
This book is readable but not much else. A more complex story, lack of vampire gimmick, tigher pacing, and characters not determined to wallow in misery would have improved this spy novel. It's head over heels better than all those idiotic vampire comedies that have been flooding the market in the last few months, but that's a back-handed compliment.
