Why are you taking up the cross and not your publisher, O'Reilly Publishers. Isn't it their job to deal with this and your job to write books? Let them be the big bad evil here.
Wow. As the husband of a woman who has written a half-dozen novels, I have to say that eldavojohn has not worked with publishing houses. No offense intended, but in my experience (limited to fiction), authors today are expected to do almost everything except for the actual printing, distribution, picking a title, and having a say in the cover art. Promotion, lining up signings, attending (and paying to attend) conventions, etc. are all on the authors' shoulders. Except for the handful of "big bet" novels that a publisher tries in any given year, authors today carry an awful lot of the weight themselves.
Pound for pound, the amoeba is the most vicious animal on earth.
