You're not too far off the mark Kenny. I think I'm going to have to experiment with a few different options and run them past those that have read the first book to see what works. I may have to reconsider my intended website layout to make sure any blurb spoiler is not visible on the list of books - that way it's a problem only if the person goes into the book detail, in which case: on their own heads be it.
Off-topic: My signature works! I had thought it might show up on old posts (just as a change of avatar does). But now I have a signature I notice the option where you can choose to display it or not. So I'm no longer anonymous, which is an important step for someone that hopes to sell a book or two.
