That inbox is very full . . .There are two sizes for the banner and the larger one fills my entire screen (actually -- I don't know where I saw the smaller one, but now the banner consistently fills my screen), so when I click on any of the thumbnail image books, the banner simply expands to fill my screen (although actually it opens a new window with the banner expanded to fill my whole screen). It took me a few goes before I scrolled down and realised it had also taken me to the thread about the 20 Exciting New Authors.
I do like the thumbnail banner (and yours) and I think it's a great idea to advertise Chrons writers, but I find the current implementation a barrier to enjoying the site (which is probably no bad thing since I spend too much time here anyway!) and may put (new) people off.
If it were narrower, I think you'd be able to advertise without blocking content, which is what it currently does. If there are too many books in the thumbnail, you could always have two thumbnail banners with half of the books on each.
This is everything I can see on my laptop:
