So many books, so little time

I cannot get enough of Cathy. She's the most interesting character in the book, in my opinion. I love how the author describes her psychopathic traits and how easily people fall to her whims. Has anyone else here read this book? What are your favorite parts and what are your thoughts on Cathy?

Some of my favorite quotes:

'In their sexual relations she convinced him that the result was not quite
satisfactory to her, that if he were a better man he could release a flood of
unbelievable reaction in her. Her method was to keep him continually off
balance. She saw with satisfaction his nerves begin to go, his hands take to
quivering, his loss of weight, and the wild glazed look in his eyes. And
when she delicately sensed the near approach of insane, punishing rage, she
sat in his lap and soothed him and made him believe for a moment in her
innocence. She could convince him.'

' Cathy learned quickly. She found him out and knew him, and once she had learned she screamed, she writhed, she cried, she begged, and she had the satisfaction of feeling the blows instantly become lighter. '
