Short Suspenseful Good Read

I enjoyed this book enough that I have purchased book #2.
It is a short read but the suspense is good.
If you have an interest in this topic – Electromagnetic Pulse (EMP) this is a good story.
If you are a serious end time prepare, you may like it – but you’ll have to read it as a novel and not as a manual. Some of the events have been greatly accelerated but it’s a novel.

I recommend this if you are looking for a quick 4-5 hr suspenseful novel.
