Widowed father and daughter, Austin and Savannah Merryman, leisurely travel the country in an old RV. As the mysterious EMP strikes, Austin and Savannah are violently separated; forced into a frightening and dangerous race for safety across two states. Austin dives into a raging river after a meeting with an old friend turns deadly, and his NSA Agent friend is gunned down. Before he dies, the NSA man passes Austin a thumb drive with no chance for an explanation. Little more is made of the USB drive in this volume other than a mob boss sends the hired killer, Zander to recover the drive. Meanwhile, Savannah panics and joins a passing family heading for Utah for safety. After recovering from his brush with death, Austin and potential love interest race to recover Savannah. We’re presented with a tense action-thriller with a little bit of everything; an EMP, hired killers, kidnapping, conspiracy, courage, perseverance, and possible romance. What else could you want; credible climax? I was given this free review copy audiobook at my request and have voluntarily left this review.
