Email is g6ypk1@yahoo.com Thank you all. You're reading my work makes my writing worthwhile. I have rewritten chapters Four and Five, so that a comprehensive and more malleable comprehension of the philosophy of the science and argument, along with the plausibility that assists the reader greatly. Back and Forth is set in 2040 and 1065-66. The disappearance of a misjudged maverick scientist in 1966; his derelict home; its purchase and full renovation brought the discovery of a clandestine laboratory and, what turned out to be a prototype Time-Machine, found in a hidden cellar. Like an out of control roller coaster my mind was racing. With this golden opportunity thrust into my hand. The time was ripe to do something about the battle at Hastings. Could this humiliation England suffered 974 years previous be reversed? The opportunity would never come again and, it was up to me to set forth and meddle with history. England shall never be invaded and lost again. Secretly, I gather scientists, engineers and close friends to advise and devise ways and means to bring about the reversal of this most ignominious defeat. Would King Harold accept help from these angels? Or are we to him, Satan's demons? What happens next? Will these Wizards from the 21st Century bring England out of the Iron Age into a peaceful, happy and enlightened environment? Will an oppressive continental regime continue to rule this land, and, if so, how could this situation be reversed? For good or evil, we must see what happens.
