I can't get into details about all these discussions, but I can reveal to you, for the first time, a few of the names that consistently pop up for Serena.

The most interesting one, for me, is Evangeline Lilly of Lost. I think she'd be terrific, but studios naturally wonder how well she'd "translate" to the big screen. She hasn't made the transition yet.

Another interesting one is Emily Blunt from Devil Wears Prada and Charlie Wilson's War. A third name I hear is Sienna Miller in brunette mode. A fourth is Eva Green from Casino Royale. Other names are the usual suspects, like Keira Knightley, although, sad to say, there is concern about the rest of them being "too old" for Serena: Rachel Weisz, Kate Beckinsale, etc.

As for Conrad Yeats, please send me your suggestions! There are so few "action" stars today in their 30s, and the most effective casting in these kinds of movies have often been unconventional choices: Tobey Maguire in Spiderman or Nicolas Cage in National Treasure or Robert Downy Jr. in Iron Man. Even Matt Damon in the Bourne movies was unexpected—and successful.

Will The Atlantis Revelation be the final Conrad Yeats story, or will he go on to new adventures?

Yes. The end of all things is here. All will be revealed next summer. In some ways the first two novels are trailers for The Atlantis Revelation. It's really exciting. And, of course, you'll be the first to get the sneak previews.

Any final words for our readers?

They are among the most intelligent out there and the first to tell me where I've got things wrong, which is more often than I'd like. In other words, they care. And I'm extraordinarily grateful.

Thank you very much for taking the time to chat with us.

My pleasure, as always.
