Congratulations to Aurelia's brother Matt, who just sold his first novel!

Amy Einhorn preempted world rights to Matthew Flaming's first novel, The Kingdom of Ohio, for her imprint at Putnam; Stephanie Cabot at the Gernert Company made the sale. Set in New York City in 1901, the book revolves around a young workman on the first subway lines beneath the city and a beautiful mathematical prodigy, as the two are drawn into a tangle of overlapping intrigues involving Thomas Edison, Nikola Tesla and J.P. Morgan. Tentative pub date is 2009, with Berkley to follow in paperback.

Sounds like one part Neverwhere and one part The Prestige. I'm sold!
