The Revival of Uncle Tom

This book is about an angry old plantation owner who was set in his own ways. He didn't want to accept his nephew's black half brother as an equal, so he had him sold to the highest bidder.
An African witch that lived in the woods asked him to reveal where the young lad was sold, but he refused. Therefore, the witch had no choice but to cast a spell on the grumpy slave master for four hundred years.
After the awakening of the slave master after over four hundred years, he was more angry than ever at how the world that he had once knew was changed. He had a hard time adjusting to the ways of the now new generation of mixed generations.
Tom wished that he'd never awakened. He was beginning to realize why the witch kept him asleep for so long. With every passing day, he wished that he was still asleep.
