Queen's Gambit by Elizabeth Fremantle

I am afraid that I couldn't continue reading this book after I finished the first chapter.  The heroine, Katherine Parr, helps her extremely sick husband to die.  I don't want to discuss euthanasia here, but I've read a lot about Katherine Parr, and this just didn't ring authentic to me.  She was too religious to consider it, and I doubt that anything like this occurred at the time.

If you are not as squeamish, the writing is vivid, and Katherine seemed likeable.
