I read this trilogy last year and enjoyed the heck out of it. I teach middle school, so I read a lot of young adult books.
Sounds like we're into the same genre. I highly recommend you read the "Gone" series, by Michael Grant. I think they're even better than Hunger Games, because in some ways they're more realistic. I think there are four books now with more on the way, but these books totally suck you in. Hard to put down!
My main criticism of Hunger Games is that the third book, Mockingjay, was way too plot-driven. The author knew what she wanted to happen, and then forced her characters to take those actions, regardless of whether or not it fit their character. I felt almost like I didn't even know any of the characters anymore. Like, what the heck is going on now? They wouldn't do that!
I took a look at the webpage for One Second After, and it looks like a cool story idea. The website is full of typos though, which makes me kind of doubtful about the author... I'll probably check it out though.
You've probably heard this before, but you should read Stephen King's Dark Tower series if you haven't yet. Ron Howard is working on a movie trilogy/TV miniseries to cover that massive story. I hope he does it justice!
