I hadn't read Suzanne Collins' run-away young adult novel, nor the other two in the trilogy at the time of the APPR announcement, but I have now, and I have to say I haven't had such a good read in a long time. (Perhaps since Harry Potter, actually ...) I can't wait to reread the entire series before the movie comes out in March 2012.
I encourage you to pick up the novel and join in on APPR. The official kick-off date is Sept. 10 at the What IF! festival, but there's no reason to wait.
And in the meantime, here's the very first movie trailer, released on MTV's Video Music Awards last night, to give you a taste of what's to come.
