Thanks to Jen Robinson for alerting me to the fact that PW's posted an image of the sequel to The Hunger Games. According to the article, Catching Fire will be published on September 8 (with a simultaneous audio edition).
Also:
Fans in the book industry can have their first chance to find out those surprises at the end of May—Scholastic will be giving out ARCs of Catching Fire at BEA in New York City.
I've never been to Book Expo America, but I'm seriously considering going this year just for the possibility of getting this book. Well, not just for that... I'm sure BEA would be all kinds of awesome. And I've never been to NYC before... Hmm. Lots to think about... ;)
