Blind Sided - The Irish End Games, #4

When the world comes crashing down around you, now more than ever, you have to believe in something.After four years of living in a post-apocalyptic world, one thing Mike and Sarah know is that nothing ever stays the same. Just when life had begun to settle down-and all their immediate needs met-a threat comes at them from a totally unexpected source. Not England or roaming bands of thugs, not the US or even the Middle East.
This time it's the land itself-the very bushes and trees of Ireland--that they'll have to protect themselves from.
