Books with title Weapon-X

In the aftermath of a devastating alien attack, there is little of anything left.

The journey to middle earth is long and treacherous with alien sentries prowling the ruinous earth and savages looking for what to eat, plunder and destroy. Tangre was a weapons developer for the Earth’s army before the war. If they are to make it alive….there would be no better time for him to utilize those skills. His ingenuity and craftiness will be the most important part of their journey. But will it be enough for them to survive the treacherous journey?
