Ooh, now I want to reread As soon as I am able, it's so great. Maybe I should make a travel collection of good long fic on my e-reader...

I found the Hunger Games totally engrossing too. Mostly the first and second book, I think - the third one seemed to aim high and not manage to hold it all together quite as impressively. Anyway, some excellent fic on the AO3 once you're done with all of them. :)
