World War Last E-BOOK

World War Last is a story of a loyal, dedicated military man and a rich philanthropist who take a strange path to solving the problems of oppression and poverty. Using newly developed bio weapons, they destroy the entire population of the word, preserving only a small selected elite group.
With the population reduced to nearly nothing, the people had robots to perform all manual tasks. They became the worst of self centered hedonists and lost all ability to do anything for themselves.
Unknown to them a very small number of people had natural immunity to the disease . These survivors formed small communities that were isolated from the elite group and the communities grew stronger over time.
Many years after the intentional destruction of society, the virus that was used mutated and attacked the descendants of the select elites. The communities of survivors were still immune to it and were unharmed. These survivors then took over the technology owned by the elites and began building a new society.

It follows one family from a powerful and elite leader to helpless descendants who are unable to care for themselves. The survivor family begins in a small community of people who find each other in the chaos after the war. The family grows to become leaders of the new society.
