I love those kinds of books too, and I actually read that one not that long ago, along with the rest of the series. I liked them a lot.

I don't know if you've heard of the Gone series by Michael Grant? It's about everyone over the age of 14 or 15 disappearing from the town and how the kids cope running everything by themselves. It was interesting. I think the series is still ongoing though, I only read the first two I think. Probably not for Meagan though, there was some stuff that freaked me out, lol.
