Free Falling — Susan Kiernan-Lewis

A fun family vacation turns into an apocalyptic nightmare in Free Falling when a couple and their young son find themselves trapped in the Irish countryside during an international crisis. With all contact outside the country gone, all electricity and all non horse-powered vehicles useless and desperate bands of outlaws roaming the Emerald Isle, the time has come for one soft American family to reach deep within for the reserve of brains and courage to survive.
