The Kindle menu doesn't have a "start reading" option, but just " go to toc" and "start at beginning." When I opened your new edition of Bleak House it opened at Chapter 1, which confused me. I had to backtrack to the book title, author's picture (which was what I was looking for to see how that had turned out), and toc. I'm guessing now it was responding to your second tag.
Since I don't especially want a book to open at the beginning text, I think the first one I try I'm going to omit that tag and see how it turns out. I'll try something without a picture, too.
Bleak House, by the way, looks terrific. I haven't read it in a while and I'll schedule it for an early re-read.
