I am trying to find a book I enjoyed reading as a teen. I can't remember the name or authors unfortunately. It was part of a short book series.
It was a post-apocalyptic story about a family that goes into cryogenic chambers in a cave to wake up hundreds of years later. They woke the children decades before the parents so that they would not have to take care of children in the uncertain future. The father had twin 45 pistols and a motorcycle and went about rendering his justice on a lawless world.
