No problem. I think the publisher would have been much better served if they had put up a few more sample chapters, to get people truly hooked. If you like your character interactions twisty you'll like it better when you get further in.

I know what you mean about sharing paperbacks - I try not to abuse my books beyond cramming them in overstuffed backpacks, but I learned the hard way that one of my favorite aunts dogears pages and sometimes leaves books facedown on tables and breaks their spines. After that, I decided all books going from me to her were gifts, to save me from pointless handwringing.
