The Alien Shadow People

An ordinary day began when Vic Smart, Jr, [called Little Vic],
decided to go fishing at his favorite lake.
The day turned out anything but ordinary. Discoveries of broken
pine limbs, a Shadow person flitting from tree to tree then walking on water, caused the young lad to leave the scene, fish,
rod and reel, all left beside the lake.
From this beginning the story of the Shadow People began and
their presence on Planet Earth would create situations with
Little Vic's family, the Smarts, and then involve learned
Individuals who became endangered trying to investigate the
Shadow People.
Discoveries that they used slaves, had enormous physical
powers, were far advanced in space craft areas, were evident from contacts finally made.
The destructive powers of the Shadow People became a National concern when in an act of retaliation they destroyed the Smart home then continued destroying National Defense locations. Needed explanations or why they were on earth, were they totally antagonistic as their exhibition of chosen destructive actions indicated, or was there a way to live with them?
