The Long Walk Home by S.A. Ison

Which would be worse? Suffering an EMP, Electromagnetic Pulse? Or finding out that you’ve fallen back into time, five hundred years. Beckett Gray thinks the world has ended because all indications lead him to believe that an EMP has struck, and he is woefully unprepared. His car and cellphone have died near the Appalachian Trail, in the Cumberland Gap National Park. Then he and several other hikers find out what has really happened! Will they survive this savage time? Can they find their home again? Or will they have to make a new home in an unforgiving time? They find out quickly that they are not welcome in this time and it is trying to kill them.
