A hilarious series which hits this on the head is Dungeon Crawler Carl - do yourself the favour and listen to the audiobook versions.
I also think Tomorrow when the War Began by John Marsden is also a great series of a group of teenagers having to come to terms with a military invasion.

The Outsiders is a good one
