I was thinking about reading this series, can someone tell me what it is basically about, please.

well,
with out any major spoilers
the Gone Series is basically about
eveyone in a small town in California
that's 15 and over disappear, in the blink of an eye. So all the kids that are left behind are trapped and trying to survive, and to make things worse animals and humans mutate.
ahh!
hope that helped :)
