Blair's father has an iron grip on her. He'll use whatever he can to get her to do what he wants, which is one good reason she can't afford real friends or any kind of happiness; he'd just take it away. A few more years... that's all she needs to survive in order to be free of him. But when her father orders her to finish a job involving Sam, (Quinn's friend, and the guy she turned down again and again despite an obvious connection between them) she'll have to get creative.
The more she gets to know Sam the more she hates herself for what she's doing to him, and the more her feelings for him turn in to something real. If she finishes the job she'll lose him forever and everyone at Whitman will know who she really is, but if she doesn't it will destroy her future and possibly land her in prison.
There is more at stake here than broken hearts for both Sam and Blair. This book will keep you on the edge of your seat waiting to see it they give in, and what it will mean if they do. The tension is delicious, and the banter gives it a perfect balance.
I don't know how she does it, but every book in the WU series is even better than the last!
