Her Name Is Beth

For a year after the biggest disaster ever to strike mankind, Dave Speer was all alone. Stranded in a tiny safe room in a house he'd gone through great lengths to make appear vacant, he led as miserable a life as any of the survivors.
Then the long winter's thaw came and he spent four weeks on the road, in a desperate attempt to locate and rescue his family.
Dave was a combat veteran. A United States Marine. He was ready and able to do whatever he had to do to get his wife and daughters back from some very bad men. He went to war with the men who'd taken them hostage. And he won.
But the reconciliation with his family wasn't what he expected. His youngest daughter Beth wasn't among them.
She'd been sold to a couple of nameless, faceless drifters.
Dave's reunion with Sarah and Lindsey was short-lived. It was a given that he'd go after little Beth. She was depending on him to rescue her. He was her only chance.
With few clues he was off again. With no help other than a few vague clues to guide him he was once again alone, once again on a vital mission. Once again facing a cruel post-apocalyptic world with no backup and someone who was relying on him for her very existence.
This is Dave's story.
