The real torture in this story is the involvement of Nan. Nan is the worst character in any of these books. She's a spoiled brat and Rush's continual need to run after her will never help her. 
 She needs the ultimatum that is she can't be civil to Blair she needs to get out of Rush's life. 
 It is more than ridiculous that Nan hates Blaire for something she discovered isn't actually Blaire's fault. It is also seriously annoying me that instead of being happy about about finding more family Nan acts like a spoiled brat. 
 Of course, Nan's father is no better. 
 Again, not great writing. Far too much cussing. But overall a decent story.
