The Mirror of Her Dreams - Stephen R. Donaldson

This book is beautifully written, I'm entranced by it, except for one aspect.  The main character is clearly being put in some sort of magical thrall by a magician ("Imager") who uses seduction to entrap and manipulate.  I literally feel sick every time there's some sort of sexual contact (largely limited to interrupted pawing, but not just).  It's such a small part of the book (so far a few pages out of 400, with another ~250 to go), but it's making it really difficult for me.
