If you liked Mockingbird, I think you’ll really like Perfect Circle, his most recent adult novel. Even though it deals with different themes, the aesthetic is similar, and the wry humor is even more pronounced. Galveston was written before Perfect Circle, and it’s more traditional fantasy — or at least more epic — but it’s also amazing. John Clute, one of the few respectable sci-fi literary critics, said it’s just shy of being one of the ten best fantasy novels ever written. I love Resurrection Man because it was the first of his books I ever read, and The Night Watch because it is beautiful, but I think his newer novels have greater mass appeal, so start with those.

More recently, Sean’s been pioneering a new form of internet storytelling, known as alternate reality gaming. (See his essay here: http://seanstewart.org/interactive/ or a great article here: http://news.cnet.com/A-novelist-turned-gaming-innovator/2100-1043_3-5995637.html)

You can wander through the archive of the Beast, the first alternate reality game, graced with what I think is still some of the best writing he’s ever done, at cloudmakers.org where they’ve lovingly preserved every website and file used in the game.

Finally, most recently, he has been attempting to combine the interactivity of alternate reality gaming with novels in two fantasy-tinged young adult mystery novels, Cathy’s Book and Cathy’s Key. Cathy’s Book made the bestseller list, and even though they’re YA, I think they’re both fun reads for adults too.

And yes, I work with him and am biased as hell, so take everything I say with a grain of salt, but if you liked Mockingbird, there’s a lot more out there where that came from.
